and 15 with α-amino-α′-diphenylphosphinoyl-substituted carbanions gave rise to the 2′-amino-substituted 3− and 2-vinylindoles 7, 12, and 17 by way of the isolable carbinols 6, 11, and 16. The heterocyclic dienes 7, 12, and 17 readily underwent Diels-Alder reactions with N-phenylmaleimide.
的反应的3- acylindoles 5,10,和15与α氨基α'-diphenylphosphinoyl取代的负碳离子引起了2'-氨基-取代的3-和2- vinylindoles 7,12,和17通过的方式可分离原醇6,11,和16。杂环二烯类7,12,和17与后行容易狄尔斯-阿尔德反应Ñ苯基马来。
