An efficient catalytic protocol for the synthesis of δ,δ-bis(aryl)-substituted β-keto esters has been developed. This method involves the Lewis acid catalysed disubstitution reaction of ester-substituted silyl enol ether acetals with a series of aromatic nucleophiles to afford valuable functionalized β-keto esters with several sites available for further derivatisation.
已开发出一种用于合成 δ,δ-双(芳基)-取代的 β-酮酯的有效催化方案。该方法涉及路易斯酸催化的酯取代甲硅烷基烯醇醚缩醛与一系列芳香亲核试剂的脱取代反应,以提供有价值的功能化 β-酮酯,其具有多个可用于进一步衍生化的位点。
