Convenient access to 4,4-disubstituted 4H-chromenes. Synthesis of 4-methyl-4-(4-methoxyphenyl)-benzo[h]-4H-chromene

Article abstract of DOI:10.1080/00397919608003841

4-Methyl-4-(4-methoxyphenyl)-benzo[h]-4H-chromene is synthesised by condensation of 4-methoxyacetophenone and ethyl acetate in strong base, followed by coupling with 1-naphthol, reduction to the epimeric lactols and elimination of water.
