of arylamines with α-keto sulfoxonium ylides bearing two aryl groups, delivering a broad range of α-tertiary aminoketones with good to excellent yields and enantioselectivities (up to 90% yield and 94% ee). The utilities of this protocol were also demonstrated by facile preparation of enantioenriched 2-amino-1,2-diarylethanol bearing two different aryl groups, a type of important building block lacking
本文公开了芳基胺与带有两个芳基的 α-酮基氧化亚叶立德的有效有机催化形式 N-H 插入反应,提供范围广泛的 α-叔氨基酮,具有良好至优异的产率和对映选择性(高达 90% 产率和 94% ee)。该协议的实用性还通过轻松制备带有两个不同芳基的 enantioenriched 2-amino-1,2-diarylethanol 来证明,这是一种缺乏有效访问的重要构建块。
