The synthesis of 9- and 6-alkylaminomethyl furoflavones 5a, b, 9a-c, 13a, b, 15a-g and 18 from the naturally occurring chromones visnagin and khellin. Gastroprotective potency of these compounds in the ethanol damage model was determined. The results indicate that, through appropriate substitution, furoflavones can be obtained that are gastroprotective.

The reaction of Lawesson's reagent (LR 5) with chalcones (4a-h) and aurones (12a-h) proceeds in refluxing toluene to give the respective benzofuranylprop-2-en-1-thiones (8a-h) and benzodifuran-3-thiones (13a-h). Correct elemental analyses and spectroscopic data were obtained for the new compounds.
