The phosphoramidite route has been used to prepare phospholipid analogues possessing biocompatible properties and the monomer 2-(methacryloyloxy)ethylphosphorylcholine, utilised in the preparation of biocompatible polymers. Modifications to established methodology include, as an alternative to the thermally unstable tetrazole, the use of 4,5-dichloroimidazole as an acid catalyst for preparing phosphite esters from the corresponding phosphoramidites, and the use of trimethylamine N-oxide as oxidant for the conversion of the phosphite esters into the corresponding phosphates.
磷酸胺酯路线已被用于制备具有生物相容性特性的磷脂类类似物,以及用于制备生物相容性聚合物的单体2-(甲基丙烯酰氧基)乙基磷酰胆碱。对已有方法的改进包括,作为热不稳定的四唑的替代品,使用4,5-二氯咪唑作为酸催化剂,以从相应的磷酸胺酯制备磷酸酯,并使用氧化三甲胺作为氧化剂,将磷酸酯转化为相应的磷酸盐。
