Successive displacement of oxybenzotriazoyl moieties from methylphosphonicbisoxybenzotriazolide by a deoxynucleoside and a mercaptan yields the O,S-dialkyl and O-alkyl-S-arylmethylphosphonothioate diastereomers which can be resolved by flash column chromatography.
通过脱氧核苷和硫醇从甲基膦酸双氧基苯并三唑基上连续取代氧基苯并三唑基部分,得到O,S-二烷基和O-烷基-S-芳基甲基硫代膦酸酯非对映异构体,可以通过快速柱色谱法拆分。
