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