An osmium-catalyzed method of addition to an olefin. In the method of asymmetric dihydroxylation of the present invention, an olefin, a chiral ligand, an organic solvent, water, an amine oxide, an osmium-containing compound and, optionally a tetraalkyl ammonium compound are combined. In the method of asymmetric oxyamination of the present invention, an olefin, a chiral ligand, an organic solvent, water, a metallochloramine derivative, an osmium-containing compound and, optionally, a tetraalkyl ammonium compound are combined. In the method of asymmetric diamination of the present invention, an olefin, a chiral ligand, an organic solvent, a metallochloramine derivative, an amine and an osmium-containing compound are combined. In one embodiment, an olefin, a chiral ligand which is a dihydroquinidine derivative or a dihydroquinine derivative, acetone, water, N-methyl morpholine N-oxide and osmium tetroxide are combined to effect asymmetric dihydroxylation of the olefin.
