Si-H insertion of a carbenoid, generated by decomposition of N2CHCO2Et, followed by a nucleophilic attack onto the Si-Cl bond by an alcohol. Alkylation of the title esters, reduction of the ester function and finally oxidation of the C-Si bond provide a facile entry to 1,2-diols.
描述了获得α-(烷氧基甲
硅烷基)
乙酸酯的简单方法及其应用。它涉及在一个罐中进行的两步序列:
铑催化类
固醇的Si-H插入,该分解是由N 2 CHCO 2 Et的分解产生的,然后是由醇对Si-Cl键的亲核攻击。标题酯的烷基化,酯官能度的降低以及最后C-Si键的氧化为1,2
-二醇提供了便捷的入口。
