ABSTRACT:
Osmium-catalyzed methods of addition to an olefin are discussed. In the method of asymmetric dihydroxylation of the present invention, an olefin, a chiral ligand, an organic solvent, water, an oxidant, an osmium-containing compound and an organic soluble anion are combined. The presence of the organic soluble anion allows the asymmetric dihydroxylation reaction to occur rapidly and the amount of olefin that is diydroxylated is high with concomitantly less chiral ligand and osmium-containing catalyst than previously achieved.
