The efficient chemical synthesis and enzymatic kinetic resolution of a family of 1-(heteroaryl)ethanamines have been performed with lipases responsible for the preparation of nitrogenated compounds in high optical purity. Thus, Candida antarctica lipase type B has been identified as an excellent biocatalyst for the stereoselective production of the corresponding enantiomerically enriched (R)-acetamides
1-(杂芳基)乙胺家族的有效化学合成和酶动力学拆分已使用脂肪酶进行,脂肪酶负责制备高光学纯度的含氮化合物。因此,Candida antarctica 脂肪酶 B 型已被确定为立体选择性生产相应对映体富集的 (R)-乙酰胺和 (S)-胺的极好生物催化剂。在反应性和对映选择性方面观察到环中杂原子的类似作用,反应一天后获得具有优异对映纯度的苯并恶唑、苯并噻唑和苯并咪唑衍生物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
