Cascade bio-hydroxylation and dehalogenation for one-pot enantioselective synthesis of optically active beta-halohydrins from halohydrocarbons

摘要

A stereoselective hydroxylation and enantioselective dehalogenation cascade reaction was developed for the synthesis of optically active beta-haloalcohols from halohydrocarbons. This cascade system employed P450 and halohydrin dehalogenase as two compatible biocatalysts, allowing a straightforward, greener and efficient access to beta-halohydrins with excellent enantioselectivities (98-99%).
