CHAIN LACTIC ACID OLIGOMER DERIVATIVE AND ITS PRODUCTION METHOD |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a new chain lactic acid oligomer derivative useful as an intermediate for synthesis of a cyclic lactic acid oligomer. SOLUTION: This lactic acid oligomer derivative is represented by general formula (I) (wherein m is an integer of≥2; Y is -COR<SP>1</SP>or -R<SP>2</SP>; R<SP>1</SP>is a substitutable aliphatic group, aryl or heterocyclic group; and R<SP>2</SP>is a substitutable heterocyclic group).
