dc.description.abstractThe synthesis of a variety of benzo[b]thiophene-4,7-quinones (4a-f) by oxidative demethylation of the corresponding 4,7-dimethoxybenzo[b] thiophenes (3a-f) with cerium(IV) ammonium nitrate is reported. Heterocycles (3a,b) were prepared by cyclization of the corresponding 2,5-dimethoxy-6-nitrobenzaldehyde (1a) and 2,5-dimethoxy-6-nitroacetophenone (1b) with methyl thioglycolate.
