Title
(EN) CHAIN LACTIC ACID OLIGOMER DERIVATIVE AND PROCESS FOR PRODUCING THE SAME
(FR) DERIVE D'OLIGOMERE D'ACIDE LACTIQUE A CHAINE ET SON PROCEDE DE PRODUCTION
(JA) 鎖状乳酸オリゴマー誘導体およびその製造方法
Abstract
(EN) A novel chain lactic acid oligomer derivative represented by the following general formula (I): wherein m is an integer of 2 or lager and Y represents -COR1 or -R2 (wherein R1 represents an optionally substituted aliphatic, aryl, or heterocyclic group and R2 represents an optionally substituted heterocyclic group). This chain lactic acid oligomer derivative is useful as an intermediate for the synthesis of a cyclic lactic acid oligomer.
(FR) L'invention concerne un nouveau dérivé d'oligomère d'acide lactique à chaîne représenté par la formule générale suivante (I) où m est un entier relatif de minimum 2 et Y représente COR1 ou R2 (où R1 représente un groupe aryle aliphatique éventuellement substitué ou un groupe hétérocyclique et R2 représente un groupe hétérocyclique éventuellement substitué). Ce dérivé d'oligomère d'acide lactique à chaîne est utile comme intermédiaire pour la synthèse d'un oligomère acide lactique cyclique.
