摘要
X-Ray analyses of 1-hydroxyyohimbine derivatives definitely show the deviation of the N(1)-O bond from the indole molecular plane. This fact supports our working hypothesis "bishomoallylic conjugation". The deviation is responsible for the rearrangement reaction in 1-hydroxyindole chemistry. Effective synthetic method for novel 7 alpha- and 7 beta-heteroarylyohimbine, and 4a alpha- and 4a beta-heteroaryl-1,2,3,4-tetrahydro-beta-carboline derivatives are reported.
