Geminal diesters, N-alkyl/aryl-2,2-bis(ethoxycarbonyl)vinylamines, were found to undergo selective hydrolysis in the presence of BF3·OEt2 at room temperature to give the corresponding half esters. Neighboring group participation by nitrogen in the hydrolysis was observed. This method is useful for the preparation of highly functionalized malonic acid half esters.
发现孪生二酯,N-烷基/芳基-2,2-双(乙氧基羰基)乙烯基胺,在BF3·OEt2存在下在室温下经历选择性水解,得到相应的半酯。观察到氮参与水解的相邻基团。该方法可用于制备高度官能化的丙二酸半酯。
