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
描述了一种新的方法,该方法通过氰化物催化的亚氨基-Stetter反应从醛亚胺合成2-乙烯基吲哚-3-乙酸衍生物,该衍生物衍生自2-氨基肉桂酸衍生物和α,β-不饱和醛。在该方案中可以使用各种类型的2-氨基肉桂酸衍生物和α,β-不饱和醛,并以高收率获得了所需的2-乙烯基取代的吲哚-3-乙酸衍生物。使用从乙醛酸酯和2-氨基肉桂酸衍生物获得的亚胺,该氰化物催化的亚氨基-Stetter反应进一步扩展到制备在2-位带有羧酸官能团的吲哚-3-乙酸衍生物。
