摘 要：<正>Polyesters,such as polylactide （PLA）,are a class of biodegradable and biocompatible polymers that have received increasing attention in biomedicine,agriculture,and commodity thermoplastics[1-2]. However,the lack of pendant functionality of conventional polyesters makes it difficult to modify and modulate the physicochemical properties in subsequent applications[3-4]. Since2006[5],the ring-opening polymerization （ROP） of O-carboxyanhydrides （OCAs）,which can be readily synthesized from amino acid or hydroxyl acid precursors,has been recognized as a promising route to functionalized polyesters[3-4]. However,due to the increased methine C-H acidity,significant racemization of the
