years with excellent results. Several chiral organocatalysts and even enzymes have proved to be resistant to milling conditions, which allows for rather efficient enantioselective transformations under ball-milling conditions. The present article reports the first example of a liquid-assisted grinding (LAG) mechanochemical enzymatic resolution of racemic β3-amino esters employing Candida antarctica lipase
在过去的十年中,已经探索了使用机械
化学进行对映选择性反应的研究,并取得了优异的成绩。几种手性有机催化剂甚至酶已被证明对研磨条件有抵抗力,这允许在球磨条件下相当有效的对映选择性转化。本文报道了利用南极假丝酵母
脂肪酶B(CALB)进行外消旋β3-
氨基酯的液体辅助研磨(
LAG)机械
化学酶促拆分的第一个实例,以高收率提供了高度有价值的对映体富集的N-苄基化β3-
氨基酸。此外,本协议易于扩展。
