α-disubstituted α-amino acid is a valuable structural motif for research in the field of bioorganic chemistry and in the development of peptide drugs. This report describes the enantioselective direct-aldol reaction of α-iminoesters with glyoxylate esters. We discovered that a catalytic amount of Co(OAc)2-pybox complex catalyzed the aldol reaction of salicylaldehyde-derived α-iminoesters with benzyl glyoxylate
