The Brook rearrangement of simple, chiral tertiary benzylic -hydroxysilanes is presented. The rearrangement followed by proton trapping is enantiospecific and proceeds with inversion of the configuration at the carbon center. Importantly, the [1,2]-Brook rearrangement can be followed by trapping of methyl or allyl electrophiles even in the protic environment, although with minimal retention of chirality
展示了简单的手性叔苄基-羟基硅烷的布鲁克重排。质子捕获后的重排是对映特异性的,并在碳中心进行构型反转。重要的是,即使在质子环境中,[1,2]-布鲁克重排之后也可以捕获甲基或烯丙基亲电试剂,尽管手性保留最少。
