to obtain optically pure boron compounds is described. The kinetic resolution of boron-containing chiral alcohols via enantioselective transesterification catalyzed by lipases was studied. Aromatic, allylic, and aliphatic secondary alcohols containing a boronate ester or boronic acid group were resolved by lipase from Candida antartica (CALB), and excellent E values (E > 200) and high enantiomeric excesses
描述了酶作为催化剂首次获得光学纯硼化合物的应用。研究了含硼手性醇通过脂肪酶催化的对映选择性酯交换反应的动力学拆分。含有硼酸酯或硼酸基团的芳族,烯丙基和脂族仲醇可通过南极假丝酵母(CALB)的脂肪酶分解,并具有出色的E值(E > 200)和高对映体过量(最高> 99%)获得底物和乙酰化产物。
