for the conversion of α,β-unsaturated carbonyls to multi-substituted benzenes using allylic phosphonium ylide reagents has been developed. The substituents and their positions on the benzene ring are controllable and predictable by the choice of an appropriate combination of α,β-unsaturated carbonyl compounds and ylides.
已经开发出一种简便的直接[3 + 3]方法,可使用烯丙基磷化叶立德试剂将α,β-不饱和羰基转化为多取代苯。通过选择适当的α,β-不饱和羰基化合物和烷基化物的组合,可以控制和预测取代基及其在苯环上的位置。
