A method is described for regioselective monoprotection of 1,n-diols. The new process depends on regioselective cleavage of orthoester, which is prepared from 1,n-diols and trialkylorthoesters. The produced mono-acetal is useful in subsequent steps as a normal acetal type protecting group.
描述了一种用于1,n-二醇的区域选择性单保护的方法。新方法取决于原酸酯的区域选择性裂解,原酸酯是由1,n-二醇和三烷基原酸酯制备的。所产生的单缩醛可在随后的步骤中用作正常的缩醛型保护基。
