  Stereochemical studies on the synthesis of 1,2,3,4-tetrahydroisoquinolin-4-ols

  摘要：

  The stereoselectivity of the acid catalyzed promoted cyclization of adequately substituted alpha-aminoaldehydes to afford a series of tetrahydroisoquinolin-4-ols is studied. The results illustrate the effect of the substituents at C-l and/or C-3 in the target heterocycle. The required precursors 5 and 10 were synthesized from the enantiomerically pure (-)-imines 1 by two different routes, and reacted with cone. HCl. (C) 1998 Elsevier Science Ltd. All rights reserved.

  A Simple and Efficient Synthetic Route to Chiral Isopavines. Synthesis of (−)-O-Methylthalisopavine and (−)-Amurensinine

  摘要：

  The isopavinan alkaloids (-)-O-methylthalisopavine (7a) and (-)-amurensinine (7d) have been synthesized in good yield and high ee from the appropriate 1,2-diarylethylamine derivatives using optically active beta-amino alcohols as chiral support. This synthetic route employs as key steps the alkylation reaction of the azomethine derivatives 2 with Grignard reagents 1 and a novel one-pot double-intramolecular cyclization of the adequately functionalized 1,2-diarylethylamines 5 to afford a series of optically active isopavines 6a-d and 7a-d.
