Preparation of a uridine derivative bearing both diethylphosphono and methanesulfonate substituents at the 3′-position has been accomplished by reaction of the corresponding α-hydroxy phosphonate with methanesulfinyl chloride and subsequent oxidation. While this methanesulfonate did not undergo elimination under standard reaction conditions, treatment with TBAF results in a novel rearrangement leading to the
通过使相应的α-羟基膦酸酯与甲亚磺酰氯反应并随后氧化,已经完成了在3'-位带有二乙基膦酰基和甲磺酸酯取代基的尿苷衍生物的制备。尽管该甲磺酸盐在标准反应条件下没有消除,但用TBAF处理会导致新的重排,从而导致相应的2'-磷酸。
