A facile, direct approach for the selective conversion of dithioester to ester functional group has been developed. In/I2 in methanol efficiently promotes the interesting functional grouptransformation at room temperature. Applying the newly developed mild conditions, a series of α-allyl-β′-oxodithioesters have been converted to the corresponding α-allyl-β′-oxoesters in moderate to good yields. Interestingly
已经开发了一种简便,直接的方法,用于将二硫酯选择性转化为酯官能团。甲醇中的In / I 2有效地促进了室温下有趣的官能团转化。应用新近开发的温和条件,一系列α-烯丙基-β'-氧代二硫代酯已以中等至良好的产率转化为相应的α-烯丙基-β'-氧代酯。有趣的是,在转化过程中,起始α-烯丙基-β'-氧代二硫代酯的二硫酯基团被选择性地转化为相应的甲酯,而该部分内的其他官能团不受影响。因此,在合成转化过程中不需要繁琐的保护-去保护。
