The enantioselective organocatalytic reduction of trifluoromethyl aryl and alkyl ketoimines afforded the corresponding fluorinated amines with high chemical and stereochemical efficiency. The Lewis base catalyzed reaction with trichlorosilane led to chiral products with a trifluoromethyl group directly linked to the newly generated stereocenter typically in >90% yield and up to 98% e.e.
三氟甲基芳基和烷基酮亚胺的对映选择性有机催化还原提供了具有高化学和立体化学效率的相应氟化胺。Lewis碱与三氯硅烷的催化反应生成具有三氟甲基的手性产物,该三氟甲基直接与新生成的立体中心相连,产率通常> 90%,ee最高可达98%
