The synthesis and directed dihydroxylation of a series of homoallylic alcohols and trichloroacetamides is described. Using the combination of OsO4 and TMEDA, moderate to high levels of stereoselectivity were obtained, depending upon the structure of the substrate. Proof of the structure of two osmate esters was obtained through X-ray crystallography.
