A highly efficient lipase AK-catalyzed direct kinetic resolution of a variety of α-allenic alcohols was developed. With the complementary to previous studies, the current reaction system is effective on a broad range of substituents (R1) at C(1), such as alkyl, aryl, alkenyl, and alkynyl groups. The Jones–Burgess empirical model was modified to interpret the reversed selectivity during the acetylation
开发了一种高效脂肪酶AK催化的多种α-烯醇的直接动力学拆分方法。作为对先前研究的补充,当前的反应系统对C(1)上的广泛取代基(R 1)有效,例如烷基,芳基,烯基和炔基。修改了Jones-Burgess的经验模型,以解释仲醇乙酰化过程中逆向选择性。烯丙醇的C(2)处的甲基暗示脂肪酶AK的催化三联体中的小结构调整,代表未来定点诱变的潜在方向。
