Enantiomerically pure lactides of l-lactide (LLA) and d-lactide (DLA) were synthesized with high yield (68.5–69.5%) via depolymerization of oligo-poly-l-lactic acid (O-PLLA) and oligo-poly-d-lactic acid (O-PDLA) catalyzed by biogenic creatinine (CR). The structures of synthesized LLA and DLA were characterized with XRD analysis of the prepared single crystals. Gas chromatograph (with a chiral stationary...
