A copper‐catalyzed method for synthesis of diaryl ketones (Ar‐CO‐Ar′) through removal of benzylic ‐CH2‐, ‐CO‐, and ‐CHR‐ groups from Ar‐CO‐CXR‐Ar′ has been discovered. A number of symmetrical and unsymmetrical heterocyclic ketones, which are usually difficult to synthesize, can be prepared in good to excellent yields. This method was applied to the synthesis of the nonsteroidal anti‐inflammatory drug
发现了一种铜催化的方法,该方法通过从Ar-CO-CXR-Ar'中去除苄基-CH 2 -,-CO-和-CHR-基团来合成二芳基酮(Ar-CO-Ar')。可以以高至优异的产率制备通常难以合成的许多对称和不对称的杂环酮。该方法适用于非甾体类抗炎药Suprofen的合成(三步收率47%)。基于初步的力学和动力学研究,提出了一种活性Cu / O 2物种来介导重排反应。
