A facile method to protect vic diols, 1,3 diols and other hydroxyl functions as methylene acetals is achieved by treating the relative substrates with POCl3 or SOCl2 in DMSO. The good yields obtained, the good solubility of many organic compounds in DMSO and the easy hydrolysis of the 1,3,5-trioxaepane derivatives prepared from trans vic diols make useful this protecting method.
通过用DMSO中的POCl 3或SOCl 2处理相对的底物,可以实现一种保护vic二醇,1,3-二醇和其他羟基作为亚甲基缩醛的简便方法。获得的良好收率,许多有机化合物在DMSO中的良好溶解性以及由反式二醇制得的1,3,5-三氧杂环庚烷衍生物的易水解性使该保护方法有用。
