A novel method for the synthesis of phosphocitrate (1, PC) starting from triethyl ester of citric acid and MeOPCl2 is described. The method is based on selective stepwise hydrolysis of ester moieties from the intermediate Me−O−P(O)(Cl)(Z) (Z = triethylcitrate), 4a, which also allows one to prepare partially esterified derivatives of PC with good yield and purity without chromatographic purifications
描述了一种从柠檬酸三乙酯和MeOPCl 2开始合成磷酸柠檬酸(1,PC)的新方法。该方法基于从中间体Me-O-P(O)(Cl)(Z)(Z =柠檬酸三乙酯)4a中选择性分步水解酯部分的方法,这也使人们可以以高收率制备PC的部分酯化衍生物和纯度,无需色谱纯化。
