摘　　要：探索了一种超声辐射下氢氧化钠催化的芳亚乙基丙二腈与二硫化碳或异硫氰酸酯的反应,方便、快速地合成了2-硫代羰基-2H-噻喃和2-氨基-6-硫代羰基二氢吡啶衍生物.本方法具有操作简单、反应时间短、产率高、环境友好等优点.产物的结构经过核磁共振氢谱和碳谱、红外及质谱进行确定.本报道的方法为合成2-硫代羰基-2H-噻喃和2-氨基-6-硫代羰基二氢吡啶衍生物提供了一条有效途径.A rapid and efficient ultrasound-assisted method for the synthesis of 2-thioxo-2H-thiopyran and 2-amino- 6-thioxodihydropyridine derivatives by the reaction of 2-（1-phenylethylidene）malononitrile and carbon disulfide or isothiocy- anatobenzene catalyzed by NaOH has been developed. This protocol has the advantages of simple operation, short reaction times, high yields, and environmental friendliness. The structures of all the products were characterized by 1H NMR, 13C NMR, IR and MS techniques. The reported method is the efficient approach for the synthesis of 2-thioxo-2H-thiopyran and 2-amino-6-thi- oxodihydropyridine derivatives.
