The enzymatic kinetic resolution of tert-butyl 2-(1-hydroxyethyl) phenylcarbamate via lipase-catalyzed transesterification reaction was studied. We investigated several reaction conditions and the carbamate was resolved by Candida antarctica lipase B (CAL-B), leading to the optically pure (R)- and (S)-enantiomers. The enzymatic process showed excellent enantioselectivity (E > 200). (R)- and (S)-tert-butyl
研究了通过脂肪酶催化的酯交换反应对 2-(1-羟乙基) 苯基氨基甲酸叔丁酯进行酶动力学拆分。我们研究了几种反应条件,氨基甲酸酯被南极念珠菌脂肪酶 B (CAL-B) 分解,产生光学纯的 (R)-和 (S)-对映异构体。酶促过程显示出优异的对映选择性(E > 200)。(R)-和(S)-叔丁基2-(1-羟乙基)苯基氨基甲酸酯很容易转化为相应的(R)-和(S)-1-(2-氨基苯基)乙醇。
