## Abstract Amino‐alkoxy‐bis(phenolate) yttrium complexes act in the presence of an excess of alcohol (up to 50 equiv. vs. Y) as highly active and stereoselective catalysts for __rac__‐lactide and __rac__‐__Ξ²__‐butyrolactone polymerizations. These versatile systems enable the production of large qu
