for the synthesis of 2-vinylindole-3-acetic acidderivatives from aldimines, which are derived from 2-aminocinnamic acidderivatives and α,β-unsaturated aldehydes, via a cyanide-catalyzed imino-Stetter reaction is described. Various types of 2-aminocinnamic acidderivatives and α,β-unsaturated aldehydes could be used in this protocol, and the desired 2-vinyl substituted indole-3-acetic acid derivatives

A protocol for the synthesis of 2-(2-nitrophenyl)indoline-3-acetic acid derivatives was developed via base-catalyzed cyclization of N-(2-nitrobenzyl)-2-aminocinnamic acid derivatives. The synthetic utility of this methodology was illustrated by the concise synthesis of dihydropaullone, a partially saturated analog of paullone. Furthermore, the indoline scaffold could be further converted to the corresponding
