| titleOfInvention | Method for producing optically active γ-lactone |
| abstract | (57) [Summary] (with correction) [PROBLEMS] To produce optically active γ-lactones at low cost and easily. SOLUTION: When an esterification reaction is carried out using a racemic hydroxyamide as a raw material and an lipase as a catalyst in an organic solvent in the presence of an acyl donor, only the optically active hydroxyamide can be efficiently esterified with a high selectivity. , Next, after separating the ester product as a reaction product from the unreacted hydroxyamide product, the ester product is hydrolyzed and cyclized to produce optically active γ-lactones. |
