Abstract
A general procedure for the osmium-catalyzed dihydroxylation of various terminal and internal olefins using bleach as cheap oxidant yields the corresponding cis-1,2-diols in the presence of dihydroquinine or dihydroquinidine derivatives (Sharpless ligands) with good to excellent chemo- and enantioselectivities under optimized pH conditions.
