Hybrid chalcones containing 1-hydroxyimidazole and chromene moieties were synthesized from 5-acetyl-1-hydroxyimidazoles and 3-formylchromenes. Application of DBU as a catalyst led to the mixtures of the target chalсones and intermediate aldols. Further interaction of the mixtures with 40% aqueous solution of sodium hydroxide in ethanol resulted in pure chalсones, isolated as trans-isomers. According to X-ray single crystal diffraction analysis, (E)-3-{3-[2-(4-fluorophenyl)-1-hydroxy-4-methyl-1H-imidazol-5-yl]-3-oxoprop-1-en-1-yl}-6-methyl-4H-chromen-4-one exists as an N-hydroxyimidazole tautomer. Its planar structure is stabilized by the intramolecular hydrogen bond between the N-hydroxy group of the imidazole and the adjacent carbonyl group. The (E)-3-{3-[2-(4-fluorophenyl)-1-hydroxy-4-methyl-1H-imidazol-5-yl]-3-oxoprop-1-en-1-yl}-6-methyl-4H-chromen-4-one molecules in crystal were head-to-tail packed.
