High levels of asymmetry can be achieved in the osmium tetroxide cis-hydroxylation of olefins by employing (-)-(R,R)-N,N,N',N'-tetramethylcyclohexane-l,2-traos-diamine as a chiral ligand for the osmium. Osmium tetroxide oxidation of olefins is an excellent method for forming vicinal diols under mil

Olefins are catalytically oxidized to glycols by osmium tetroxide in the presence of organic selenoxide cooxidants. Glycols were obtained in good yields from mono-, di-, tri-and tetrasubstituted olefins. Osmium tetroxide is widely used as a catalyst for the cis-dihydroxylation of olefins in conjunct

## Treatment of pyrodelphinine (1) with osmium tetroxide afforded a mixture of the cis-hydroxylation product 2 and an unexpected product 3 in the mtio of 4:1, respectively. Similar'ly, o&dation of deZpkinine (51 afforded a-oxodetpkinine 16; 75%) and oxidation
