undergone a facile and efficient allylic nucleophilic substitution reaction with X, S, N, and O-nucleophiles to afford functionalized tetrasubstituted alkene appended oxindoles in very good yield. The MBH adducts and their acetates on treatment with halides, saturated and unsaturated amines, thiols, and trialkyl orthoformates afforded allyl halide, allyl amine, allyl thio-ether and allyl ether derivatives
衍生自靛红和马来酰亚胺的Morita-Baylis-Hillman加合物已经与X,S,N和O-亲核体进行了简便有效的烯丙基亲核取代反应,从而以很高的收率提供了官能化的四取代烯烃附加的吲哚。用卤化物,饱和和不饱和胺,硫醇和原甲酸三烷基酯处理的MBH加合物及其乙酸酯分别提供了烯丙基卤,烯丙基胺,烯丙基硫醚和烯丙基醚的吲哚。
