method for the chemoselective esterification of phenolic alcohols is described. The reaction overcomes the tyranny of protection, and capitalizes on the activation of acyl halides with cerium(III) chloride to selectively esterify alcohol hydroxyls in the presence of phenolic ones. The generality of the reaction was demonstrated with a series of phenolic alcohols of dietary relevance (vanillol, hydroxytyrosol
描述了一种温和且操作简单的酚醇化学选择性酯化方法。该反应克服了保护的专制,并利用了氯化铈(III)活化酰基卤来在酚类羟基的存在下选择性酯化醇羟基。一系列具有饮食相关性的酚醇(香草醛,羟基酪醇,表儿茶素)证明了该反应的普遍性,从而迅速进入了一系列与生物医学研究相关的化合物,其中一些以前只能通过酶促方法获得。
