POLYMERIZATION OF 1-AZABICYCLO[4.2.0]OCTANE WITH CHIRAL TRICYCLIC AMINO ACID ESTERS FOR OBTAINING BIOMEDICAL MATERIALS

Abstract

The cationic ring-opening polymerization of 1-azabicyclo[4.2.0]octane, commonly called conidine (1) was studied with some chiral tricyclic amino acid esters (6a-6f) as acylation agents to obtain optically active biopolymers (8a-8f) of the different masses. The structures of the new compounds were confirmed by FT-IR, UV and NMR, and the distribution index of the molecular weights of the polymers was determined from SEC measurements.
