The organic Lewis base-catalysed asymmetric allylic alkylation of 3-substituted oxindoles with Morita-Baylis-Hillman carbonates is reported, affording multifunctional oxindoles with adjacent quaternary and tertiary chiral centres (dr up to 92 : 8, 86-97% ee).
据报道,有机的路易斯碱催化的三取代的羟吲哚与森田-贝利斯-希尔曼碳酸盐的有机不对称烯丙基烷基化反应,提供了具有相邻季铵和叔手性中心的多官能羟吲哚(dr高达92:8,86-97%ee)。
