A straightforward procedure leading to the new phosphonylating reagent, methyl 4-toluenesulfonyloxymethylphosphonate, requiring no chromatographic purification is described. This stable reagent works with the same efficiency as dimethyl and other dialkyl esters for the introduction of an O-phosphonomethyl moiety while, in contrast to dimethyl ester, it does not cause any unwanted methylation of sensitive
描述了一种无需新的色谱纯化方法即可直接产生新的膦酰化试剂4-甲苯磺酰氧基甲基膦酸甲酯的方法。对于引入O-膦酰基甲基部分,该稳定的试剂与二甲基和其他二烷基酯具有相同的效率,而与二甲基酯相反,它不会引起敏感官能团的任何不希望的甲基化。举例说明了其以高产率用于被保护的核苷的烷基化的效用。
