Abstract Herein we report a facile synthesis of esters of bis‐α‐aminoalkylphosphinic acids obtained by an addition of Cbz‐protected phosphinic analogues of amino acid methyl esters to an appropriate imine in refluxing benzene. Complete deprotection of the esters could be achieved in one step by the action of 30% HBr in acetic acid.
摘要 在此,我们报告了通过在回流苯中将 Cbz 保护的氨基酸甲酯的次膦酸类似物添加到适当的亚胺中获得的双-α-氨基烷基次膦酸的酯的简便合成。通过在乙酸中的 30% HBr 的作用,可以一步实现酯的完全脱保护。
