A process for preparing an optically active phenyloxirane compound represented by formula (II), wherein ring A is a substitued or unsubstituted benzene ring; R is a group represented by -CO2R<q>, or a group convertible to the group represented by -CO2R<q>, wherein R<q> is an ester residue; and * indicates an asymmetric carbon atom, comprising treating a styrene derivative (I) represented by the formula (I), wherein ring A and R are the same as defined above, with an asymmetric oxidation agent formed from a chiral ketone compound and an oxidizing agent, or a chiral dioxirane compound. |
