Abstract
An optically active lactone compound is produced by using a Zr(salen) complex of the following formula (I) or its enantiomer as a catalyst and subjecting a cyclic ketone compound to a Baeyer-Villiger reaction with at least one oxidizer selected from hydrogen peroxide, aqueous hydrogen peroxide and urea-hydrogen peroxide adduct in a solvent: wherein Ar1 is an aryl group having a carbon number of 10 to 16 and Y is a phenoxy group or an alkoxy group having a carbon number of 1 to 10.
Claims16
A method of producing an optically active lactone compound, which comprises using a Zr(salen) complex represented by the following formula (I) or (II):
- wherein Ar1 is an aryl group having a carbon number of 10 to 16 and Y is a phenoxy group or an alkoxy group having a carbon number of 1 to 10 as a catalyst in a solvent, and conducting a Baeyer-Villiger reaction of a cyclic ketone compound with at least one oxidizer selected from the group consisting of hydrogen peroxide, aqueous hydrogen peroxide and urea-hydrogen peroxide adduct.
A Zr(salen) complex represented by the following formula (I) or (II):
- wherein Ar1 is an aryl group having a carbon number of 10 to 16 and Y is a phenoxy group or an alkoxy group having a carbon number of 1 to 10.
