The Cu-catalyzed aerobic oxidative esterification of simple ketones via C-C bond cleavage has been developed. Varieties of common ketones, even inactive aryl long-chain alkyl ketones, are selectively converted into esters. The reaction tolerates a wide range of alcohols, including primary and secondary alcohols, chiral alcohols with retention of the configuration, electron-deficient phenols, as well
已经开发了通过 CC 键裂解的 Cu 催化的简单酮的有氧氧化酯化。各种常见的酮,甚至是惰性的芳基长链烷基酮,都被选择性地转化为酯。该反应耐受多种醇,包括伯醇和仲醇、保留构型的手性醇、缺电子酚以及各种天然醇。使用廉价的铜催化剂、广泛的基材范围以及中性和露天条件使该协议非常实用。(18)O 标记实验表明,在这种转化过程中发生了氧化作用。初步机制研究表明,该过程主要涉及两条新途径。

The first copper-catalyzed direct β-functionalization of saturatedketones is reported. This protocol enables diverse ketones to couple with a wide range of nitrogen, oxygen and carbon nucleophiles in generally good yields under operationally simple conditions. The detailed mechanistic studies including kinetic studies, KIE measurements, identification of reaction intermediates, EPR and UV-visible
