sulfoxidation reactions on a set of aromatic sulfides. With a few exceptions, excellent enantioselectivities in the synthesis of chiral phenyl and benzyl sulfoxides were achieved. The bacterial Baeyer–Villiger monooxygenase was also shown to accept racemic sulfoxides, a prochiral diketone and an organoboron compound as substrates. This study demonstrates the great biocatalytic potential of this novel oxidative
来自荧光假单胞菌ACB的重组4-羟基苯乙酮单加氧酶(HAPMO)已作为一组芳族硫化物的硫氧化反应的催化剂进行了测试。除少数例外,在手性苯基和苄基亚砜的合成中获得了极好的对映选择性。细菌Baeyer-Villiger单加氧酶也被证明可以接受外消旋亚砜,前手性二酮和有机硼化合物作为底物。这项研究证明了这种新型氧化酶的巨大生物催化潜力。
