OLIGOLACTIC ACID ESTER CONTAINING CARBOXYMETHYL GROUP ON SIDE CHAIN

摘要

PROBLEM TO BE SOLVED: To synthesize a chain or cyclic oligolactic acid ester containing a carboxymethyl group on the side chain. SOLUTION: A chain oligolactic acid ester containing a carboxymethyl group on the side chain is firstly synthesized and then subjected to cyclization reaction by intramolecular dehydration condensation to synthesize a cyclic oligolactic acid ester containing a carboxymethyl group on the side chain.
