and convenient synthetic protocols based on H-phosphonate chemistry have been developed for the preparation of nucleoside 5′-diphosphates. It consists of oxidation of the silylated H-phosphonate monoesters in pyridine with iodine to produce the corresponding N-pyridiniumphosphonate intermediates, followed by their reactions with orthophosphoric acid used as a nucleophile. The added value of the method
摘要 已经开发了一种基于 H-膦酸酯化学的简单方便的合成方案,用于制备核苷 5'-二磷酸。它包括在吡啶中用碘氧化甲硅烷基化的 H-膦酸酯单酯以产生相应的 N-吡啶鎓膦酸酯中间体,然后它们与用作亲核试剂的正磷酸反应。该方法的附加值是反应的底物 H-膦酸酯单酯可以由相应的核苷原位制备,无需分离即可用于下一步。该方法简单,适用于核糖和脱氧核糖核苷的各种二磷酸盐及其类似物的制备。图形概要
