Abstract
An efficient and easy method for one-pot three-component synthesis of 1,3-disubstituted-3H-benzo[f ]chromenes by the condensation of naphtol, aromatic aldehyde derivatives and phenylacetylene in the presence of ferric hydrogensulfate [Fe(HSO4)3], has been described. The catalyst displayed high activity which afforded the corresponding 1,3-disubstituted-3H-benzo[f ]chromenes in satisfying yields. Alkyl-substituted phenols were examined and the corresponding benzopyran derivatives were synthesized in moderate yields. Heterogeneous nature of the using catalyst made it reusable for further chemical reactions.
