Merging both C–H and C–C activation in a tandem process is a marked challenge. A novel Rh(III)-catalyzed C–H activation/ring opening C–C cleavage/cyclization of carboxylic acids with cyclopropanols was developed for the synthesis of 3-substituted phthalides and α,β-butenolides. This reaction displays excellent functional group tolerance with respect to both carboxylic acids and cyclopropanols and features
在串联过程中合并C–H和C–C激活是一个显着的挑战。开发了一种新型的Rh(III)催化的C–H活化/开环C–C裂解/与环丙醇的羧酸环化反应,用于合成3-取代的邻苯二甲酸酯和α,β-丁烯内酯。该反应对羧酸和环丙醇均显示出优异的官能团耐受性,并且具有相对温和的条件。值得注意的是,该方法的实用性通过后期功能化快速构建带有3-取代邻苯二甲酸酯骨架的生物活性化合物而突显出来。
