Sodium chlorite is an efficient stoichiometric oxidant in Sharpless asymmetric dihydroxylation. The conversion of styrene was achieved twice as fast as in the established Sharpless K3[Fe(CN)6] dihydroxylation. Eight olefins were dihydroxylated to corresponding vicinal diols with yields and ees as good as those reported in the literature for other similar processes.
