Herein, we report an exceedingly mild method for the direct, transition-metal-free esterification of thioamides through the selective generation of tetrahedral intermediates. The method represents the first transition-metal-free approach to the thioamide to thionoester transformation in organic synthesis. This reactivity has been accomplished through N,N-Boc2-thioamides that engage in ground-state
在此,我们报告了一种极其温和的方法,通过选择性生成四面体中间体来直接、无过渡
