Route Towards New Heteroaromatic Benzo[1,4]dioxine Derivatives
2H-[1,4]benzodioxino[2,3-c]pyrrole- and thieno[3,4-b][1,4]benzodioxine derivatives were synthesized via nucleophilic aromatic substitution reactions of halogenated benzene derivatives with the corresponding 3,4-dihydroxythiophene or pyrrole derivatives.
