The enzymatic kinetic resolution of a broad set of β‐amino ketones was investigated by using a collection of 16 Baeyer–Villiger monooxygenases from different bacterial origins, which display various substrate specificities. Within this platform of enzymes excellent enantioselectivities (E>200) were found towards aliphatic and aromatic 4‐amino‐2‐ketones, and some enzymes even showed opposite enantioselectivity
通过收集来自不同细菌来源的16种Baeyer-Villiger单加氧酶的集合,研究了广泛的β-氨基酮的酶促动力学拆分,这些酶具有不同的底物特异性。在这种酶的平台上,发现对脂肪族和芳香族的4-氨基-2-酮具有极好的对映选择性(E > 200),有些酶甚至表现出相反的对映选择性。中间体β-氨基烷基乙酸酯经过自动水解,生成光学纯的β-氨基醇,它们是合成天然药物和医药行业高度关注的生物活性化合物的关键中间体。此外,在某些情况下,形成了异常的酯。
