another molecule of aniline and ethylglyoxylate. With this method, a series of chiral α,β-diamino acid derivatives were efficiently constructed in good yields and with good to excellent diastereo- and enantioselectivities. A highlydiastereo- and enantioselective four-component reaction of a diazo ketone with two molecules of anilines and ethylglyoxylate was achieved under Rh2(OAc)4 and chiral phosphoric
