✦ Synopsis

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 mild conditions with a minimum of side reacti0ns.l The oxidation can be carried out

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
