l-2-oxazolin-5-ones and 4-arylmethylene-2-styryl-2-oxazolin-5-ones react with primary aromatic amines in the presence of anhydrous zinc chloride to give the corresponding 4-arylmethylene-2-methyl-2-imidazolin-5-ones and 4-arylmethylene-2-styryl-2-imidazolin-5-ones (5) respectively. Treatment of 5 with phosphorus pentasulfide gives the corresponding 2-imidazoline-5-thiones. Reaction of 4-arylmethyl
化合物4-芳基亚甲基-2-甲基-2-恶唑啉-5-酮和4-芳基亚甲基-2-苯乙烯基-2-恶唑啉-5-酮在无水氯化锌存在下与芳香伯胺反应得到相应的4-芳基亚甲基-2-甲基-2-咪唑啉-5-酮和 4-芳基亚甲基-2-苯乙烯基-2-咪唑啉-5-酮 (5)。用五硫化二磷处理 5 得到相应的 2-咪唑啉-5-硫酮。4-芳基亚甲基-2-苯基-2-恶唑啉-5-酮与盐酸羟胺反应得到相应的咪唑啉酮,再与卤代烷和酰氯反应得到相应的醚和酯。所得产品的结构已根据元素分析、IR 和 UV 数据进行表征。
