Compounds 2, 3, 4, 7, 10, 11, 12 and 13 were formed via the reactions of [3-(4-chlorophenyl)oxiranyl]thiophen-2-yl-propanone with hydrazine derivatives, hydroxyl-amine hydrochloride, thiourea, thiosemicarbazide, carbon disulfide, phenyl isothiocyanate, methyl isothiocyanate and phosphorus pentasulfide, respectively. Pyrimidine derivative 4 was in turn used as precursor for preparation of thiazolopyrimidines
化合物 2、3、4、7、10、11、12 和 13 是通过 [3-(4-氯苯基) 环氧乙烷基]噻吩-2-基-丙酮与肼衍生物、盐酸羟胺、硫脲、氨基硫脲、二硫化碳、异硫氰酸苯酯、异硫氰酸甲酯和五硫化二磷。嘧啶衍生物 4 又用作制备噻唑并嘧啶 5 和 6 的前体。 用 D-葡萄糖和树糖处理 Pyrazolothioamide 7,得到相应的腙8 和 9。
