Patent ID: 7812184

Claim:
A production method of an optically active epoxy compound of formulae (7), (8) or (9) wherein R 3 is hydrogen atom or methyl group, R 4 and R 5 are hydrogen atom, or R 4 and R 5 together form —CH 2 —, —CH 2 CH 2 —, —CH 2 CH 2 CH 2 — or —CH 2 O— (the oxygen atom in the —CH 2 O— is bonded at R 5 side), R 6 is a phenyl group, R 7 is methyl group or ethyl group, the carbon atom shown with * is optically active, characterized by comprising subjecting an unsaturated compound of formula (4), (5) or (6) wherein R 3 , R 4 , R 5 , R 6 and R 7 are as defined above, to asymmetric epoxidation with a peracid by using as a catalyst an optically active titanium complex of formula (1) or (1′) wherein R 1 is a phenyl group (the phenyl group is substituted with methyl group, ethyl group (the methyl group and the ethyl group are substituted with at least one halogen atom) or C 1-7 alkoxy group), R 2 is C 3-5 divalent group in which two R 2 s together form a ring, M is TiJ 1 J 2 (in TiJ 1 J 2 , Ti is titanium atom, J 1 and J 2 independently of each other are a halogen atom or C 1-4 alkoxy group, J 1 J 2 represents an oxygen atom, or J 1 and J 2 together form a ring that is a divalent group of formula (2) (a partial structure O-E-O in the formula is shown by formula (3) in the compound of formula (1) and by formula (3′) in the compound of formula (1′) wherein R 1 and R 2 are as defined above)).
