| titleOfInvention | β-substituted-γ-butyrolactones and method for producing the same |
| abstract | The present invention provides a method for producing β-substituted-γ-butyrolactones and a β-substituted-γ-butyrolactone compound. Kind Code: A1 A β-substituted-γ-succinic anhydride represented by the general formula (2) is reacted with a zinc borohydride in a suitable solvent such as tetrahydrofuran, methylene chloride, dichloromethane or ethyl acetate by a corresponding general formula. (S)-or (R) -β-substituted-γ-butyrolactone represented by the general formula (1) or a racemic mixture thereof represented by the general formula (1), which is converted into β-substituted-γ-butyrolactone represented by (1): Production method. Wherein R 1 is hydrogen, acetyl, benzyl, benzoyl, 2- or 4-nitrophenylcarbonyl, 2- or 4-bromophenylcarbonyl, 2- or 4-chlorophenylcarbonyl or 1- or 2-naphthylcarbonyl is there.)
