A series of 2-substituted 3-(toluenesulfonamidoalkyl)indoles was synthesized by application of (EtO)2POH or iodine as the catalyst, and was hydrogenated using chiral Pd catalyst, giving the 2,3-disubstituted indolines with up to 97% ee.
以(EtO)2POH或
碘为催化剂合成了一系列2-取代的3-(
甲苯磺酰
氨基烷基)
吲哚,并使用手性Pd催化剂进行氢化,得到2,3-二取代的二氢
吲哚,其ee高达97%。
