interest in synthetic chemistry, biological process and pharmaceutical industry. Transition-metal, luxury ligand or excess base were always vital to the transformation. Here, we developed a transition-metal-free hydrogen-bond-assisted esterification of amides with only catalytic amount of base. The proposed crucial role of hydrogen bonding for assisting esterification was supported by control experiments

配体或过量的碱对转化始终至关重要。在这里,我们开发了仅催化量碱的无过渡
金属的氢键助酰胺化酰胺。控制实验,密度泛函理论(DFT)计算和动力学研究支持了氢键在协助酯化中所起的关键作用。除了广泛的底物范围和出色的官能团耐受性外,该碱催化方案还补充了传统的过渡
金属催化的酰胺酯化反应,并为有机合成和制药行业催化裂解酰胺CN键提供了新途径。
