a set of racemic 1,2-diols with an ester functional group are prepared, starting from α-ketoesters in a three-step procedure with moderate yields. The racemic 1,2-diols, containing a chiral quaternary center in their structure, are subjected to selective acylation in order to perform their kinetic resolution catalysed by a set of commercially available lipases. Under optimized reaction conditions
光学活性的1,2-二醇是有机合成中的重要组成部分。在本文中,从α-酮酸酯开始,以三步法制备了一组具有酯官能团的外消旋1,2-二醇,收率适中。外消旋的1,2-二醇在其结构中包含手性季中心,经过选择性酰化处理,以执行由一组可商购的脂肪酶催化的动力学拆分。在优化的反应条件下,通过使用洋葱假单胞菌的脂肪酶PSL-C在叔丁基甲基醚中获得良好的转化率和对映选择性。这种生物催化剂最多可以重复使用五次而不会失去其性能。
