for the enantioselective epoxidation of both tertiary allylic and homoallylic alcohols catalyzed by Hf(IV)-bishydroxamic acid (BHA) complexes is described. Asymmetric epoxidation, kinetic resolution, and desymmetrization have been developed, demonstrating the flexible nature of the Hf(IV)-BHA system. This is the first report in which these substrates were obtained with enantioselectivities of up to
描述了一种由 Hf (IV)-双异羟肟酸 (BHA) 配合物催化的叔烯丙醇和高烯丙醇的对映选择性环氧化的有效且通用的方法。不对称环氧化、动力学拆分和去对称化已经得到发展,证明了 Hf(IV)-BHA 系统的灵活性。这是获得这些底物的对映选择性高达 99% 的第一份报告。
