Abstract

Some naphthoquinone and anthraquinone ketals have been prepared by anodic oxidation. Regioselective hydrolysis of the above diketals into monoketals is also described. Diels- Alder reaction of (E)-1-methoxybuta-1, 3-diene with the monoketal of 1, 4-dihydro-4, 4- dimethoxy-5-benzyloxynaphthalene proceeded in a regioselective manner.
