Enantiomerically pure N,N'-bis[2-(4,5-dihydrooxazol-2-yl)phenyl]oxalamides are readily prepared from 2-(2-aminophenyl)-4,5-dihydrooxazoles and oxalyl chloride. The structures of the corresponding nickel and copper complexes were determined by X-ray analysis. Ruthenium complexes, prepared in situ from RuCl3 and the corresponding ligands, catalyze the enantioselective epoxidation of trans-stilbene to afford trans-1,2-diphenyloxirane with up to 69% ee. The cobalt complexes were tested as catalysts in Michael reactions of malonates with chalcone (up to 89% ee).
