A desymmetrization of prochiral diesters with a chiral phosphoric acid catalyst produces highly enantioenriched lactones in excellent yield. Various substitution patterns are tolerated, many of which result in the generation of an enantioenriched all-carbon quaternary center. Manipulation of the lactone products to useful small building blocks is also described.
