In this protocol, we report a Mo-catalyzed anti-dihydroxylation of secondary allylic alcohols, providing a general method for the preparation of 1,2,3-triols bearing up to three continuous stereocenters with excellent diastereocontrol. The mechanistic studies reveal that this dihydroxylation reaction consists of two steps and up to excellent diastereomeric ratios of the final triol products can be achieved due to the high level of both diastereocontrol in the initial epoxidation and regiocontrol in the following hydrolysis in situ.

A catalytic hydroxyl-directed anti-dihydroxylation of allylic and homoallylic alcohols has been developed. This operationally simple method was successfully applied to the direct anti-monodihydroxylation of allylic alcohols containing at least one distal olefinic unit. Under the catalysis of commercially available MoO2(acac)2, an array of hydroxylated dienes were successfully converted into various 1,2,3-triols using hydrogen peroxide as an environmentally benign oxidant under aerobic conditions, notably, in complete regioselectivities and in the most cases in diastereospecific pathway.
One-pot synthesis of 1,2,3-triols from allylic hydroperoxides and a catalytic amount of OsO4 in aqueous acetone

Allylic hydroperoxides were converted into the corresponding triols in the presence of a catalytic amount of OsO4. The present reaction involves regeneration of active osmium species by the hydroperoxide functionality and occurs in a diastereoselective manner to form triols in high yields. A plausible mechanism for the formation of 1,2,3-triols from allylic hydroperoxide is presented.
