Naoto Chatani studied chemistry at Osaka University and received his Ph. D. in 1984
under the guidance by Profs. Noboru Sonoda and Shinji Murai. In 1984 he joined the
Institute of Scientific and Industrial Research at Osaka University and worked in the
laboratory of Prof. Terukiyo Hanafusa. After postdoctoral studies (1988-1989 under Prof.
Scott E. Denmark, the University of Illinois, Urbana-Champaign), he moved back to
Osaka University and worked with Prof. Shinji Murai as Assistant Professor. He was
promoted to Associate Professor in 1992 and Professor in 2003. His research interests
center on the area of catalysis. Awards:Young Chemist Award of the Chemical Society of
Japan (1991). The fourth Green and Sustainable Chemistry Award: Minister of Education,
Sports, Culture, Science and Technology Prize (2005).

Stereoselective Synthesis of Tetrahydroisoquinolines and Tetrahydrobenzazepines
from Phthalan and Isochroman

Many tetrahydroisoquinoline1 and tetrahydrobenzazepine natural products are cytotoxic
agents that display a wide range of biological activities. For these reasons, the
development of new synthetic strategies which allow access to these heterocycles is of
interest to the pharmaceutical industry. The stereoselective synthesis of 3-substituted
1,2,3,4-tetrahydroisoquinolines (3, n = 1) and 2-substituted 2,3,4,5-tetrahydro-1Hbenzo[d]azepine (3, n = 2) was achieved starting from phthalan (1, n = 1) or isochroman
(1, n = 2) and chiral N-tert-butylsulfinyl aldimines, through a two-pot strategy: (1)
Reaction of the dianionic intermediate 4 resulting from the reductive opening lithiation of
phthalan2 or isochroman (1)3 with chiral aldimines in the presence of ZnMe2 to give
compounds 2 with high diastereoselectivity (dr 71:29-86:14) and (2) cyclization of the
aminoalcohol resulting from the removal of the tert-butylsulfinyl unit in enantiomerically
pure compounds 2.4 Regarding the stereochemistry of the major stereoisomer 2, it was
unambiguously determined by single X-ray analysis. Nucleophilic addition takes place to
the Re-face of the imine in the case of (Rs)-sulfinylimines. Hexahydropyrroloisoquinoline
6, hexahydropyridoisoquinoline 7 and octahydrobenzopyrroloazepine 8 were accessible
through this methodology starting from O-tetrahydropyranyl protected hydroxylimines 5,
taking place a final double cyclization.
