A new method for the catalytic aldol reaction to ketones, using CuF.3PPh3.2EtOH complex as the catalyst and (EtO)3SiF as the additive, is described. The reaction can be applied to a wide range of ketones and trimethylsilyl enolates. On the basis of mechanistic studies, a working hypothesis for the catalytic cycle is proposed, in which the dynamic ligand exchange mediated by copper silicates produces
介绍了一种以 CuF.3PPh3.2EtOH 配合物为催化剂、(EtO)3SiF 为添加剂的催化醛醇反应生成酮的新方法。该反应可应用于范围广泛的酮和三甲基甲硅烷基烯醇化物。在机理研究的基础上,提出了催化循环的工作假设,其中由硅酸铜介导的动态配体交换产生活性烯醇铜。此外,本反应可以扩展到使用 tol-BINAP 作为手性配体的催化对映选择性反应。
