A novel synthetic strategy toward the asymmetric synthesis of vicinal diols bearing a tertiary center is presented. The method encompasses the dinuclear Mg-catalyzed asymmetric addition of ethyl diazoacetate into several aldehydes, oxidation of the diazo functionality, and diastereoselective alkyl transfer of various organometallics into the resulting chiral β-hydroxy-α-ketoesters to afford a diverse
提出了一种新的合成策略,用于不对称合成带有三级中心的邻二醇。该方法包括双核 Mg 催化重氮乙酸乙酯不对称加成到几种醛中,重氮官能团的氧化,以及各种有机金属的非对映选择性烷基转移到所得的手性 β-羟基-α-酮酯中,以提供不同范围的 1,2 -高产率、非对映选择性和手性转移的二醇。
