  摘要：

  A general method for synthesizing mixed phosphonate diesters from monoesters using (1H-benzotriazol-1-yloxy)tris(dimethylamino) hexafluorophosphate or (1H-benzotriazol-1-yloxy)tripyrrolidinophosphonium hexafluorophosphate reagents is described. The reaction proceeded through a benzotriazolyl ester as shown by comparison with other reagents such as DCC, DCC/DMAP, DCC/1-hydroxybenzotriazole, bromotris(dimethylamino)phosphonium hexafluorophosphate, or O-(1H-benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate and by P-31 NMR analysis. This benzotriazolyl phosphonic ester intermediate was more reactive toward alcohols than toward amines, contrary to its carboxylic analogue.

  phosphotriesterase and 15 mutant enzymes. For each substrate, the leaving group was 4-hydroxyacetophenone while the other two groups attached to the phosphorus core consisted of an asymmetric mixture of methyl, methoxy, ethyl, ethoxy, isopropoxy, phenyl, phenoxy, cyclohexyl, and cyclohexoxy substituents. For the wild-type enzyme, the relative rates of hydrolysis for the two enantiomers ranged from 3 to 5.4 x 10(5)

  The hydrolysis of phosphonates by alkali in aqueous dioxane has been studied. The symmetrical phosphonates are hydrolysed with loss of one ester group to form a monoacid. With the mixed phosphonates the better leaving group is replaced.

  substituents of the phosphonate esters, the conversion to the corresponding phosphonic acids can be achieved under milder conditions in the absence of water (the dry process). Thus, the conversion of dibenzyl phosphonates to the corresponding phosphonic acids took place smoothly at 80 °C in toluene or benzene in high yields. Moreover, selective conversion of benzyl phosphonates RP(O)(OR′)(OBn) to the

  已经开发了通过布朗斯台德酸催化的将膦酸酯转化为膦酸的“湿”法和两种“干”法。因此，在水的存在下，通常可以在140°C的温度下，通过三氟甲基磺酸（TfOH）催化，将一系列烷基，烯基和芳基取代的膦酸酯水解成相应的膦酸，产率高（湿法）。另一方面，使用膦酸酯的特定取代基，可以在没有水的条件下在较温和的条件下实现向相应膦酸的转化（干燥过程）。因此，在80℃下在甲苯或苯中以高收率平稳地进行了二苄基膦酸酯向相应膦酸的转化。此外，也可以在反应条件下将苄基膦酸酯RP（O）（OR'）（OBn）选择性转化为相应的单膦酸RP（O）（OR'）（OH）。通过生成二异丁烯进行脱烷基叔丁基膦酸酯和TfOH的相关催化即使在室温下也能以高至高收率得到相应的膦酸。Nafion对这些反应也显示出高催化活性。通过使用Nafion作为催化剂，可以通过简单的方法容易地大规模制备膦酸。
