Abstract
ω-(2, 6-Dimethyl-4-pyrimidinylthio-(4), 2-methyl-4-quinazolinylthio-(9), and 4-oxo-2-quinazo- linylthio)-(10) acetophenones with hydrochloric or perchloric acid provide 2, 5-diaryl-1, 4- dithiins (7) whereas α)-(6-methyl-4-pyrimidinylthio) acetophenones (11) with aq HCl/HClO4, or POCl3 followed by hydrolysis provide 1-(4-aryl-2-thiazolyl)-2-propanones (12). Likewise, 2-(6-methyl-4-pyrimidinylthio) cyclohexanone (13) give the thiazole derivative (14).
