developed to synthesize axially chiral phosphorus allenes through a PPS-catalyzed asymmetric Pudovik addition followed by phospha-Brook rearrangement. Mechanistic experiments have demonstrated that the enantio-determining step is the 1,2-addition, with the subsequent rearrangement undergoing a central-to-axial chirality transfer.
我们开发了一种有效且实用的方法,通过 PPS 催化的不对称 Pudovik 加成,然后进行
磷-布鲁克重排来合成轴向手性
磷丙二烯。机理实验表明,对映体决定步骤是 1,2-加成,随后的重排经历中心到轴的手性转移。
