Abstract
A new method for the synthesis of 2-vinylindole-3-acetic acid derivatives from aldimines, which are derived from 2-aminocinnamic acid derivatives and α,β-unsaturated aldehydes, via a cyanide-catalyzed imino-Stetter reaction is described. Various types of 2-aminocinnamic acid derivatives and α,β-unsaturated aldehydes could be used in this protocol, and the desired 2-vinyl substituted indole-3-acetic acid derivatives were obtained in high yields. This cyanide-catalyzed imino-Stetter reaction was further extended to the preparation of indole-3-acetic acid derivatives bearing a carboxylic acid functionality at the 2-position, using aldimines obtained from glyoxylates and 2-aminocinnamic acid derivatives.
