Four ketoreductases (KREDs) were identified for the enantioselective synthesis of β-hydroxysulfides. KRED311 and KRED349 catalyse the synthesis of β-hydroxysulfides bearing a stereocentre at the C−O bond with opposite absolute configurations via chemoenzymatic cascades from thiophenols/thiols and α-haloketones/alcohols. KRED253 and KRED384 catalyse the synthesis of β-hydroxysulfides bearing a stereocentre
鉴定了四种酮还原酶 (KRED) 用于 β-羟基硫化物的对映选择性合成。KRED311 和 KRED349 通过苯硫酚/硫醇和 α-卤代酮/醇的化学酶级联催化合成在 C-O 键处具有立体中心且绝对构型相反的 β-羟基硫化物。KRED253 和 KRED384 通过外消旋 α-硫代醛的动态动力学拆分 (DKR) 催化合成在 C-S 键处具有立体中心并具有相反对映选择性的 β-羟基硫化物。
