kinetic resolution of 2-substituted indoline derivatives was achieved by hydrogen transfer to imines by means of a chiral phosphoric acid catalyst. The oxidative kinetic resolution was applicable to racemic alkyl- or aryl-substituted indolines, and the remaining indolines were obtained in good yields with excellent enantioselectivities.
2-取代二氢吲哚衍生物的氧化动力学拆分是通过手性磷酸催化剂将氢转移到亚胺来实现的。氧化动力学拆分适用于外消旋的烷基或芳基取代的二氢吲哚,并且以良好的收率和优异的对映选择性获得了剩余的二氢吲哚。
