An enantioselectivecarbonyl–enereaction of glyoxylate esters with 1,1-disubstituted alkenes catalyzed by chiral cationic dirhodium(II,III) carboxamidates is described. The paddlewheel dirhodium(II,III) carboxamidates having one open coordination site at each rhodium smoothly catalyze the carbonyl–enereaction to afford homoallylic alcohol products in good isolated yields with high enantioselectivities
