Abstract
A highly efficient synthesis of cis-diol compounds through cis-dihydroxylation of olefins using osmate (VI) salt as catalysts is disclosed, which has found important application in efficient large-scale preparation of, among others, α,α-cedranediol from α-cedrene.
Claims23
A method of preparing a diol compound from an olefin, the method comprising oxidation of the olefin with an oxidant in the presence of a catalytic amount of an osmate (VI) salt in one or more solvent(s) at an elevated temperature.
