ABSTRACT:
The present invention relates to methods for the synthesis of chiral non-racemic products, e.g., enantiomerically-enriched hemiesters, from prochiral and meso starting materials, e.g., prochiral and meso cyclic anhydrides. The present invention also relates to catalysts for the aforementioned methods, and methods for synthesizing these catalysts.
