A highly regio- and enantioselective insertion of vinyl diazoacetates into O–H bonds of carboxylicacids has been realized by cooperative catalysis of an achiral rhodium complex and a chiral phosphoric acid. The insertion reaction exhibits highly carbenic reactivity rather than vinylogous reactivity, representing a rare example towards α-acyloxyl-β,γ-unsaturated esters, and the corresponding esters
