Contrary to the accepted convention, this work shows that Minisci-type C–H alkylation does not require any metal, photocatalyst, light, or prefunctionalization of the readily available and inexpensive carboxylic acids to proceed well under mild conditions. These mild conditions can be utilized for late-stage alkylations of complex molecules, including pharmaceutical compounds and light-sensitive compounds
与公认的惯例相反,这项工作表明,Minisci型C–H烷基化不需要任何金属,光催化剂,光或易于获得的廉价羧酸的预官能化,即可在温和条件下顺利进行。这些温和的条件可用于复杂分子的后期烷基化,包括在光催化条件下降解的药物化合物和光敏化合物。
