  Stereospecific Synthesis of trans, cis-1,3,4-Trisubstituted 1,2,3,4-Tetrahydro-b-Carbolines

  摘要：

  Pictet-Spengler condensation of N(bb)-benzyl-beta-methyltryptophan methyl ester (2RS,3SR;4) with aldehydes followed by debenzylation afforded trans, cis-1,3,4-trisubstituted 1,2,3,4-tetrahydro-beta-carbolines in complete stereospecific fashion. Tetrahydro-beta-carbolines (6a) and (6b) were prepared by the direct condensation of beta-methyltryptophan methyl ester (4) with the corresponding aldehydes. The stereochemistry of the products was confirmed by an X-ray analysis of 6a.
