Photochemical synthesis of heteroatom‐containing polycyclic aromatic compounds

Abstract

Abstract Anthra[2,1‐ b ]furan, anthra[2,1‐ b ]benzo[ d ]furan, anthra[2,1‐ b ]thiophene, anthra[1,2‐ b ]thiophene, anthra[2,1‐ b ]benzo[ d ]thiophene, anthra[2,1‐ b ]pyrrole and naphtho[2,3‐ c ]carbazole derivatives were synthesized in fairly good yields by a one‐pot photocycloaddition reaction of 2,3‐disubstituted 1,4‐naphthoquinone with 1,1‐diarylethylene. This is the first reported synthesis of these aromatic compounds.
