Biodegradable α-hydroxyl polyesters,such as poly(lactic acid)(PLA)and poly(lactic-co-glycolic acid)(PLGA)were investigated as scaffolds for tissue engineering.However,polymeric materials on the basis of lactide are l...
4-(2-Benzyloxyethoxycarbonyl)-2-oxetanone, an β-substituted-β-lactones with latent pendent hydroxyl groups,was synthesized from L-aspartic acid. Firstly, bromosuccinic acid was synthesized from L-aspartic acid and i...
