A cinchona-alkaloid catalyzed asymmetric Kornblum DeLaMare rearrangement has been developed. Thus, enantioenriched 4-hydroxyenones are prepared from dienes by a two-step sequence involving photochemical dioxygenation and chiral base-catalyzed desymmetrization of the resulting endoperoxides.

meso-Diol 4, derived from 1,5-cyclooctadiene, in the presence of Pseudomonas cepacia lipase in isopropenyl acetate, afforded enantiopure 5, an attractive intermediate for the synthesis of sugars and related compounds.
