Abstract

The regio- and enantioselective hydrolysis of several phenyloxiranes catalyzed by soluble epoxide hydrolase (sEH) was investigated using recombinant human, mouse or cress sEH. Results indicate that human and mouse sEH enantioselectively hydrolyze (S,S)-alkyl-phenyloxiranes faster than the (R,R)-alkyl-phenyloxiranes investigated in this study, while cress sEH displayed opposite enantioselectivity. Preparation of pure (2R,3R)-3-phenylglycidol from the racemic mixture was achieved with a 31% yield using human sEH as catalyst. The sEH enzymes were found to be regioselective at the benzylic carbon of the phenyloxiranes, supporting the proposed mechanism in which one or more tyrosine residues in the active site of the enzyme act as a general acid catalyst in the alkylation half reaction.
