The synthesis of a novel series of eleven 6-aryl(5-methyl)-4-trifluoromethyl-2(1H)-pyrimidinones, where aryl=Ph, 4-CH3Ph, 4-FPh, 4-ClPh, 4-BrPh, 4-OCH3Ph and alkyl=H, CH3, from the reaction of 4-aryl-4-methoxy-1,1,1-trifluoro-3-buten-2-ones with urea in the presence of hydrochloric acid, is reported. Trifluoroacetylation of acetophenone- and propiophenone-dimethylacetals derived from phenones, was
合成一系列新的11种6-芳基(5-甲基)-4-三氟甲基-2(1 H)-嘧啶酮,其中芳基= Ph,4-CH 3 Ph,4-FPh,4-ClPh,4-由4-芳基-4-甲氧基-1,1,1-三氟-3-丁烯-2-酮与尿素在盐酸存在下反应制得的BrPh,4-OCH 3 Ph和烷基= H,CH 3,据报道。衍生自苯酮的苯乙酮-和苯乙酮-二甲基缩醛的三氟乙酰化用于获得前体。
