A family of chiral zinc amido-oxazolinate complexes are shown to be highly active and isoselective initiators for the ring-opening polymerization (ROP) of rac -lactide, yielding isotactic stereoblock polylactides (PLA) with P m up to 0.91. This represents the highest isoselectivity observed with zinc-based catalysts for ROP of rac -lactide.
