摘要
X-Ray analyses of 1-hydroxyyohimbine derivatives clearly show the deviation of the N(1)-O bond from the indole molecular plane. This phenomenon supports our working hypothesis "bishomoallylic conjugation". The deviation is responsible for the unprecedented nucleophilic substitution reaction in 1-hydroxyindole chemistry and effected the synthesis of novel 7 beta-heteroarylyohimbine and 4a alpha-heteroaryl-1,2,3,4-tetrahydro-beta-carboline derivatives from the corresponding 1-hydroxyindole derivatives.
