The esterification of activated amides, N-acylsaccharins, under transition-metal-free conditions with good functional group tolerance has been developed, resulting in C–N cleavage leading to efficient synthesis of a variety of esters in moderate to good yields. This work demonstrates that esterification may proceed by using simple N-acylsaccharins, haloalkanes, and Cs2CO3 as oxygen source.
已开发出在无过渡金属条件下进行的活化酰胺酯化反应,具有良好的官能团容忍性,导致C-N键裂解,从而高效合成各种酯类产物,收率在中等到良好之间。这项工作表明,酯化反应可以通过使用简单的N-酰基糖胺、卤代烷烃和Cs2CO3作为氧源来进行。
