A new approach toward the asymmetric synthesis of optically active trifluoromethylated amines was enabled by an unprecedented, highly enantioselective catalytic isomerization of trifluoromethyl imines with a new chiral organic catalyst. Not only aryl but also alkyl trifluoromethylated amines could be obtained in high enantioselectivities.
一种新方法通过一种前所未有的、高对映选择性的手性有机催化剂对三氟甲基亚胺的异构化反应,实现了光学活性的三氟甲基化胺的不对称合成。不仅芳基,而且烷基三氟甲基化胺也可以以高对映选择性获得。
