The Michael addition of 3-substituted oxindoles to nitroolefins was catalyzed by a novel tartrate-derived guanidine in high yield with excellent diastereo- and enantioselectivity. This method showed an extraordinarily broad substrate scope in terms of both reaction partners.
3-取代的氧吲哚与硝基烯烃的迈克尔加成反应在一种新型的酒石酸衍生的胍的催化下,以高产率和优异的非对映选择性及手性选择性进行。该方法在反应底物方面显示出了极其广泛的适用性。
