A photocatalytic methodology for the single step synthesis of γ-ketoacids from α-ketoacids has been developed. This method employs maleic anhydrides as traceless synthetic equivalents of acrylic acids, achieving a selective cross-coupling via a dual decarboxylative strategy, where molecular CO2 is released as the only waste byproduct. The method has also been expanded to incorporate a highly regioselective
开发了一种从 α-酮酸一步合成 γ-酮酸的光催化方法。该方法采用马来酸酐作为丙烯酸的无痕合成等价物,通过双重脱羧策略实现选择性交叉偶联,其中分子CO 2作为唯一的废物副产物被释放。该方法还得到了扩展,可将高度区域选择性的三组分与各种醇偶联,以获得功能化的 γ-酮酯。
