• Chirality-Matched Cyclopropenimine–Thiourea Organocatalysis for Regiocontrolled Ring-Opening Polymerization of Methyl Glycolide (2026) · ACS Catalysis · doi

  Chirality-matching strategies based on enantiopure monomers and chiral catalysts have been pursued in both organometallic catalytic and organocatalytic systems; however, the presence of metal residues remains a significant limitation, whereas organocatalytic approaches still lack a fundamental mechanistic understanding of site selectivity and fail to achieve a unified control over reaction conditions, rates, and regioselectivity.
