Results A large work of organic synthesis allowed the preparation of several chelating ligands. These ligands or cavitands belong to two families: resorcinarenes and calixarenes (Figures 1 and 2). A- Synthesis of Modified Resorcinarenes. The synthetic scheme for the resorcinarene cavitands presented in Figure 1, shows that tetrabrominated cavitand III constitute the intermediate from which we synthesized another cavitands by nucleophilic substitution. Figure 1 A-1. Synthesis of cavitands I, II and III The compound I was prepared as described by Cram et al (prix Nobel 1989), methylresorcinol and acetaldehyde are mixed in stoichiometric proportions in a mixture of water and ethanol and in the presence of HCl, the cavitand I is obtained with a high 90% yield similar to that mentioned in the literature. 4102 برنامج دعم البحوث العلمية Grant Program for Scientific Research in Lebanon – 2014 8 We transform cavitand I to cavitand II with conic structure by introducing a methylene bridge using CH2Cl2. In the literature bromochloroethane (CH2BrCl) was used as described by Cram et al [Cram, D. J.; Karbach, S.; Kim, H-E.; Knobler, C. B.; Maverick, E. F.; Ericson, J. L.; Helgeson, R. C. J. Am. Soc. 1988, 110, 2229-2237]. In fact, the dichlormethane CH2Cl2 used as a solvent in many chemical reactions, it has two advantages: - Replaces Bromochloromethane which destroys the ozone layer; and whose production has been banned since 1st January 2002, at the Eleventh Meeting of the Parties of Montreal Protocol on the substances that deplete the ozone layer. - The dichloromethane is less expensive and available in large quantities. The cavitand II was obtained by our method with very good yield (84 %) much better than that obtained by Cram’s group. Afterthat, a bromination reaction was performed using N- bromosuccinimide (NBS) in tetrachloromethane as already described [Sorrell, T. N.; Pigge F. C. J. Org. Chem. 1993, 58, 784-785]. The yield of the reaction was improved by using distilled CCl 4, and thus we reached up to 79%, better than that obtained by the literature (60%). A-2. Synthesis of cavitand IV (tetra-azide) and cavitand V (tatramine) To achieve the synthesis of cavitand IV using sodium azide NaN3, we have adopted a method developed in our laboratory using acetone as solvent in place of DMF or DMSO. This reaction is done properly, no side products or impurities were obtained, and a simple filtration followed by evaporation of the solvent affords the desired product with a very good yield (85%). At the same time, in order to prepare a cavitand substituted with triazole group for the oxidation catalysis with iron, Hooley’s group have published very recently (2012), the synthesis of a compound similar to cavitand IV, their method consist of using THF as a solvent mixed with a solution of NaN3 in DMSO [K. E. Djernes; O. Moshe; Mr. Mettry; D. D. Richards; Hooley R. J. Org. Lett. 2012, 14, 788-791] This method allows to obtain the corresponding compound with good yield but it is more complicated than our method. 4102 برنامج دعم البحوث العلمية Grant Program for Scientific Research in Lebanon – 2014 9 Furthermore, acetone is much less toxic and less odorous than THF and DMSO and it is elimination by evaporation is easier. The cavitand V was prapared in our Lab by reduction under hydrogen of the the tatraazide cavitand IV, The hydrogenation reaction is catalyzed by platinum on charcoal (Pt/C, 5%). An amino resorcinarene, similar to cavitand V is used recently by Sheela et al (2011) as a stabilizer for the dispersion of nanodiamands in organic solvents for the purpose of growing diamond films. [V. P. Sheela; W. Xiao; S. Han; X. Zhou; S. Albin; R. Balasubramanian, J. Mater. Chem., 2011, 21, 6395-6400]. This group uses synthetic procedures already described in the literature to prepare the cavitand tetra amines in two steps from tetra brominated cavitand. This method enables the transformation of the tetra brominated cavitand into tetrakis (phthalimidomethyl), and then the phthalimido group is hydrolyzed by hydrazine hydrate under reflux in ethanol / THF. Our method seems to be cleaner and much simpler and affords the product V with a very high yield (95%). A-3. Synthesis of cavitands VII and VIII We have prepared the cavitand VII by two different methods: the first method described in the literature by our collaborator [Pellet-Roasting, S.; Nicod, L.; Chitry, F.; Lemaire, M. Tetrahedron lett. 1999, 40, 8793-8796] consists on the conversion of III (tetra bromide) to cavitand VII using KCN in DMSO at 70°C during 24h. The cavitand VII was obtained with a yield of 55%. The second method we developed consists on the using of a mixture of acetone and acetonitrile as solvents instead of DMSO. This method which allowed us to obtain the desired product VII in a much better yield of 75%, and was carried out using solvent less toxic, more friendly and easily removed by evaporation. The cyano groups of VII are then hydrolyzed under reflux in basis medium in a mixture EtOH: H2O (1:1) to give the cavitand VIII with four groups of carboxylic acid in good yield (70%). [Pellet-Roasting, S.; Nicod, L.; Chitry, F.; Lemaire, M. Tetrahedron lett. 1999, 40, 8793-8796]. The trials to prepare cavitands VI and IX are failed, in both cases we obtained a white solid not soluble in any solvents, that is why we did not arrived to characterized theses solids. B- Synthesis of Calixa(4)arene moieties: 4102 برنامج دعم البحوث العلمية Grant Program for Scientific Research in Lebanon – 2014 10 The synthetic schemes for the calixarene macrocylcles (R = H or t-butyl) presented in Figure 2, shows the synthesis method correspond to the cyclization by traditional nucleophilic substitution. Figure 2 B-1. Synthesis of Calixa(4)arene moieties (1), (2) and (3) 4102 برنامج دعم البحوث العلمية Grant Program for Scientific Research in Lebanon – 2014 11 The compound (1) was prepared as described in the literature [Francoise A.; Elizabeth M. C.; Mary D.; George F.; Stephen J. H.; Branko K.; Alan J. L.; M. Anthony M.; Elizabeth M.; Barbara L. R; Marie J. S; and Eileen M. S. J. Am. Chem. Soc., 1989, 111, 8681-8691], it is obtained in high yield (78%). The compound (2) was prepared by alkylation of the left two phenolic groups by MeI in DMF in the presence of NaH as a base to give the pure compound in 70 % yield after column chromatography. The obtained compound (2) was further reduced with LiAlH4 in THF at room temperature for 12 hrs to give its corresponding diethyl alcohol (3) in 60 % yield. B-2. Mitsonobu coupling: Synthesis of compound (4) The Mitsunobu reaction is very famous reaction since it can be used to convert primary or secondary alcohols into various other functional groups such as ether esters, amines, amides, lactams, lactones. As described by [Abidi, R.; Oueslati, I.; Amri, H.; Thuery, P.; Nierlich, M.; Asfari, Z.; Vicens. J. Tetrahedron Lett. 2001, 42, 1685–1689]. One of the objectives of our research is to screen the best condition for the Mitsunobu reaction by varying the coupling reagents and the trialkyl/triaryl phosphines, and the temperature of the reaction. The nucleophilic substitution of the two hydroxyl groups can be done by refluxing together both the calixarene (3) and triprotected diethylene triamine (Figure 3) under Mitsunobu condition as described by [J. Hovinen, R. Sillanpää. Tetrahedron Letters, 2005, 46, 4387–4389]. The reaction to prepare the compound (4) was carried out in the presence of the coupling reagent diethyl azadicarboxylate and triphenyl phosphine in THF, the progress of the reaction was followed by TLC which showed many spots corresponding to the desired product, the side products, the coupling reagents, triphenyl phosphine and triphenyl phosphine oxide. Furthermore all the purification trials, precipitation, crystallization, even flash chromatography failed to purify the desired product. One efficient way to follow such reaction is to inject it in HPLC at different instants. 4102 برنامج دعم البحوث العلمية Grant Program for Scientific Research in Lebanon – 2014 12 RR RR RR Ns NH HN sN N sN MeO O MeO O HO RR PPh3, DEAD THF Reflux MeO O MeO O Ns N HO N sN N sN (4) (3) Figure 3 In Mitsunobu reaction the hydrogen of sulfonamide group must be acidic enough in order to be deprotonated easily by the coupling reagent, then the amino groups were protected by a highly electron withdrawing group such as o-nitrobenzene sulfonyl group, therefore the diethylene triamine (DETA) was protected by reacting it with slight excess amount (little more than three equivalents) of o-nitrobenzene sulfonylchloride in THF and in the presence of NaHCO3 as a base (Figure 4). In this reaction we improved the condition for the triprotection of (DETA) described by [Jean-Michel Siaugue; Fabienne Segat-Dioury; Alain Favre-Reguillon; Charles Madic; Jacques Foosa and Alain Guyb. Tetrahedron Lett., 2000, 41, 7443–7446] in which we refluxed the reaction mixture at 400C rather than at room temperature, to obtain the desired product in better yield 85% with shorter reaction time 50 hrs rather than 96 hrs. Also we purified the resulting triprotected (DETA) as crystals by slow precipitation from a binary mixture of ethanol and dichloromethane. Figure 4 B-3. Synthesis of Calixa(4)arene moieties (5) and (7) The compound (5) was synthesized by direct nucleophilic substitution of the ester groups of compound (1) by the amine groups of the triamine (DETA) as described by [Abidi, R.; 4102 برنامج دعم البحوث العلمية Grant Program for Scientific Research in Lebanon – 2014 13 Oueslati, I.; Amri, H.; Thuery, P.; Nierlich, M.; Asfari, Z.; Vicens. J. Tetrahedron Lett. 2001, 42, 1685–1689]. The macrocyle (5) was obtained in high yield (95%). The amide groups of the compound (5) are subjected to reduction using LiAlH4 to prepare their resulting amines (7), the reaction is done in diethylether according to the procedure described by [K. No; H. J. Lee; K. M. Park; S. S. Lee; K. H. Noh; S. K. Kim; J. Y. Lee; and J. S. Kim; J. Heterocyclic Chem., 2004, 41, 211]. Figure 5 B-4. Synthesis of Calixa(4)arene (8) Regarding to the effectiveness of the compound (5) in the field of extraction of metallic cations from contaminated water as described in [Abidi, R.; Oueslati, I.; Amri, H.; Thuery, P.; Nierlich, M.; Asfari, Z.; Vicens. J. Tetrahedron Lett. 2001, 42, 1685–1689], we decided to go on further to prepare a compound similar to (5) but with two macrocycles on the lower rim similar in structure to PCTA. To do this, we first inserted four ethylacetate groups on the four phenol groups of the starting calixarene, by refluxing together the calixarene with ethyl bromoacetate at 700C, to direct our substitution toward tetra-alkylation and to prevent obtaining a mixture of di, tri, and tetra alkylated products, Na2CO3 was used instead of K2CO3, in acetone instead of MeCN, leading us to improve the procedure of this reaction over the procedures described by [Francoise A.; Elizabeth M. C.; Mary D.; George F.; Stephen J. H.; Branko K.; Alan J. L.; M. Anthony M.; Elizabeth M.; Barbara L. R; Marie J. S; and Eileen M. S. J. Am. Chem. Soc., 1989, 111, 8681-8691], as we added 5 equivalent of ethylbromoacetate instead of 40 equivalent described in the literature and we obtained the good product (8) with higher yield and shorter reaction time. 4102 برنامج دعم البحوث العلمية Grant Program for Scientific Research in Lebanon – 2014 14 B-5. Synthesis of Calixa(4)arene moiety (9) Compound (8) is reacted with two equivalents of (DETA) at 800C in a binary mixture of toluene/methanol to produce its corresponding bicyclic tetra-amide derivative (9) in good yield (75%), Figure 6. Figure 6 C. Conclusion During these 2 years, we have synthesized 8 cavitands of resorcinarene and 7 cavitands of calixarene. Synthetic procedures have been modified and improved; it allows us to obtain good yields, to use less expensive and toxic solvents and to reduce the reaction times. – Tetrakis (aminomethyl) calix-4-resorcinarene V is obtained according to a synthetic route consists of five steps. Our alternative method to those described in the literature consists of preparing the tetrakis (azidomethyl) calix-4-resorcinarene IV and then reducing under hydrogen atmosphere. – Bromochloromethane is banned worldwide because it destroys the ozone layer, and we replaced it by dichloromethane during the preparation of the intermediate II. This procedure also allows obtaining a good yield, and usage of less dangerous solvents for the environment. – The synthesis of cavitand IV in acetone using NaN3 has two major advantages over the recently described method by Sheela et al (2012) [27]. The Sheela group used NaN 3 in a solution of THF/DMSO. Acetone which has an acceptable dielectric constant can dissolve sodium azide, easier to evaporate, less toxic and facilitates purification of the final product. – Also concerning the calix(4)arene we improved the procedures for the preparation of 4102 برنامج دعم البحوث العلمية Grant Program for Scientific Research in Lebanon – 2014 15 compounds 5, 7, and 9. 1. During the preparation of compound 5 we used exactly 1:1 equivalents of both calixarene diethylester and DETA in a diluted solution 10-1 mol/L, and by giving the reaction the necessary time (12 hrs) it proceed with complete conversion. Therefore there is no need to purify the compound by flash column as described by the literature, evaporating the solvent under reduced pressure was enough to give the pure product with excellent yield up to 100%. 2. In the literature [J. Heterocyclic Chem., 2004 41, 211] they prepared the compound 7 by using large excess amount of LiAlH4 and after quenching the reaction by H2O it gives heavy white precipitate which avoid the separation of the two layers (H2O/CH2Cl2) during extraction, instead of this we made filtration first to get rid of the precipitate, and then extraction by CH2Cl2. Moreover the compound did not elute from the column chromatogaraphy as they describe and it is normal since it contains three amine groups, instead of this a simple recrystallization from a mixture of ethyl acetate and cyclohexane was more evident. 3. While the procedure to prepare the compound 9 was improved by using only slight excess amount of ethyl bromoacetate (1.1 equivalent) instead of 100% molar excess described in [J. Am. Chem. Soc., 1989, 111, 8681-8691], and we got a pure product with the same yield within shorter reaction time. We will consider for further work: The introduction of other functional groups such as amide, sulfonamides, ureas. Preparation of triazamacrocycles derived from calixarenes, and reduce the resulting amides into their corresponding amines, and finally introduce acetic acid groups on the resulting amines. Screen the best conditions for the Mitsunobu reaction Evaluation of the ligands towards: - Lanthanide extraction (strategic metals) - Heavy metal extraction (pollutants) Liquid/liquid extraction Membrane filtration 4102 برنامج دعم البحوث العلمية Grant Program for Scientific Research in Lebanon – 2014 16 6.
