The direct transformation of MOM-protected alcohols into the corresponding acetates by acetic anhydride/ferric chloride in CH2Cl2, in a one-step process and good to excellent yields, is reported. The reaction has been applied to a variety of substrates and occurs with retention of configuration.
据报道,
乙酸酐/
三氯化铁在
CH2Cl2 中一步法直接将 MOM 保护醇转化为相应的
乙酸酯,收率良好甚至极佳。该反应适用于多种底物,并能保留构型。
