More Information
Summary:PROBLEM TO BE SOLVED: To provide a method for producing a wine lactone and a method for producing an intermediate extremely effective for producing the wine lactone and to provide application techniques of the wine lactone. SOLUTION: The method for producing a compound (wine lactone) represented by formula (6) comprises a step (A) for obtaining a compound represented by formula (2) by carrying out an alkyl addition reaction with a compound represented by formula (1), a step (B) for obtaining a compound represented by formula (3) by carrying out a reduction reaction of a carbonyl group by using oxazaborolidine as an asymmetric catalyst, a step (C) for obtaining a compound represented by formula (4) by carrying out hydrolysis of an ester part of the compound represented by formula (3), a step (D) for obtaining a compound represented by formula (5) by carrying out lactone cyclization reaction of the compound represented by formula (4) with DCC (dicyclohexylcarbodiimide), a step (E) for obtaining the compound represented by formula (6) by carrying out methylation reaction of the compound represented by formula (5).
