WIPO Patent Application WO/2005/077882
Kind Code:

Abstract:
A chain or cyclic oligolactate having an aminoethyl, hydroxyethyl, or carboxymethyl group in a side chain. A chain oligolactate having an aminoethyl, hydroxyethyl, or carboxymethyl group in a side chain is synthesized first. This chain oligolactate is subjected to cyclization by intramolecular dehydrating condensation. Thus, a cyclic oligolactate having the substituent, e.g., aminoethyl, in a side chain can be synthesized.
