synthetic accessibility of amides render them valuable precursors for the synthesis of diverse nitrogen-containing compounds. Herein, we present a metal-free and streamlined synthetic strategy for the synthesis of quaternary α-aminophosphonates. This approach involves sequential deoxygenative nucleophilic phosphonation and versatile electrophilic alkylation of secondary amides in a one-pot fashion. Notably
酰胺的广泛存在和合成可及性使其成为合成各种含氮化合物的宝贵前体。在此,我们提出了一种用于合成 α-氨基膦酸季盐的无金属且简化的合成策略。该方法涉及一锅法中仲酰胺的连续脱氧亲核磷酸化和多功能亲电烷基化。值得注意的是,该方法首次实现了仲酰胺与亲核试剂和亲电试剂的直接双官能化,通过简单的衍生化,通过水解产生有价值的游离α-氨基膦酸酯。该协议具有操作简单、功能组广泛兼容性、环境友好以及可扩展到多克数量的优点。
