An efficient two-step procedure for the preparation of 2-arylthiochroman-4-ones has been developed. Thus, 3-aryl-1-(2-halophenyl)prop-2-en-1-ones, prepared by the condensation between 1-(2-halophenyl)ethanones and aromatic aldehydes in ethanol at room temperature, were treated with sodium hydrogensulfide in DMF at 80 ˚C to give 2-arylthiochroman-4-ones in good overall yields.
