This communication describes the design and execution of a novel approach to forming chiral lactones via C−H bond activation. The strategy features an unprecedented enantioselective Rh-catalyzed hydroacylation of carbon−oxygen double bonds. Representative keto-aldehydes (derived from salicylaldehyde) undergo cyclization with complete regioselectivity to afford seven-membered lactones in great enantiomeric
