esterification and etherification of alcohols, leveraging a Sc(OTf)3-catalyzed ring-strain release event in the meticulously designed, chromatographically stable mixed anhydrides or benzyl esters that incorporate an intramolecular donor–acceptor cyclopropane (DAC). This versatile method facilitates the straightforward functionalization of sugar, terpene, and steroid alcohols under mild acidic conditions,
我们在此公开了一种用于醇的酯化和醚化的高效方案,利用 Sc(OTf) 3催化的环应变释放事件,在精心设计的、色谱稳定的混合酸酐或苄酯中结合了分子内供体-受体环丙烷(数模转换器)。这种多功能方法有利于糖、萜烯和类固醇醇在温和酸性条件下的直接官能化,正如糖二醇的单催化剂驱动的双重保护所证明的那样。
