Abstract

The hydroxy- and carbonyl-derivatives of 9-oxabicyclo[3.3.1]nonane have been synthesized through an economic and green catalytic reaction between cycloocta-1,5-diene (COD) and aqueous H2O2 with tungstic acid as the catalyst. This process has advantages from the viewpoint of green chemistry, in that the aqueous H2O2 is used as the green oxygen donor, the only by-product of H2O2 is water and the tungstic acid catalyst can also be easily recovered. The excellent yields of the object products (1 and 2) (see Scheme 1) are reached easily under mild reaction conditions.
