Method for producing cyclic diketone compound

Abstract

Provided is a method for producing a compound represented by general formula (I) by oxidative cleavage of a compound of formula (II), which is a bicyclic tetrasubstituted olefin compound, using hydrogen peroxide. The method for producing a compound represented by general formula (I) includes a step of subjecting a compound represented by general formula (II) to oxidative cleavage using hydrogen peroxide in the presence of an acid catalyst or in the presence of a tungstic acid compound to obtain the compound represented by general formula (I): [In the formulae, formula -A1- (where the front bond denotes a bond that bonds with a carbon atom C1 while the back bond denotes a bond that bonds with a carbon atom C2) is an alkylene group having 2 to 6 carbon atoms that may have been substituted and that may further include an ether bond, an ester bond, a secondary amino group, a thioether group, or these, and formula -A2- (where the front bond denotes a bond that bonds with a carbon atom C1 while the back bond denotes a bond that bonds with a carbon atom C2) is an alkylene group having 4 to 10 carbon atoms that may have been substituted and that may further include an ether bond, an ester bond, a secondary amino group, a thioether group, or these.]
