The Cu-catalyzed novel aerobic oxidativeesterification reaction of 1,3-diones for the synthesis of α-ketoesters has been developed. This method combines C-C σ-bond cleavage, dioxygen activation and oxidative C-H bond functionalization, as well as provides a practical, neutral, and mild synthetic approach to α-ketoesters which are important units in many biologically active compounds and useful precursors
已开发出用于合成 α-酮酯的 Cu 催化的新型 1,3-二酮有氧氧化酯化反应。该方法结合了 CC σ-键裂解、双氧活化和氧化 CH 键功能化,并为 α-酮酯提供了一种实用、中性和温和的合成方法,α-酮酯是许多生物活性化合物中的重要单元和各种有用的前体。功能组转换。在机理研究的基础上提出了一个合理的激进过程。
