A diazo-, metal-, and base-free multi-substituted hydrazone synthesis via a formal reductive N–H bond insertion reactions of hydrazones to α-keto esters has been developed. The protocol features a broad substrate scope and good functional group tolerance, providing N–H bond insertion products in moderate to excellent yields. Moreover, P(III)-mediated N–H functionalization of pharmaceutical containing
                                    通过腙与 α-
酮酯的正式还原 N-H 键插入反应,开发了一种无重氮、无
金属和无碱的多取代腙合成方法。该方案具有广泛的底物范围和良好的官能团耐受性,以中等至优异的产率提供 N-H 键插入产品。此外,还成功实现了P(III)介导的含有腙部分的药物的N-H功能化。  全尺寸图像
