Abstract
6-Amino-1-aryluracils (11a-g), 6-amino-1-aryl-2-thiouracils (12a-g), a nd 6-amino-1,3-diaryl-2-thiouracils (6a,b) have been synthesised throu gh the dry hydrogen chloride gas-catalysed condensation of ethyl cyano acetate (7) with appropriate arylureas and thioureas. 1-Aryl (12a-g) a rid 1,3-diaryl-2-thiouracils (6c-g) have been converted to the corresp onding 1-aryl (15a-g) and novel hitherto unreported, 1,3-diaryluracils (5a-e) through their oxidative desulphurisation.
