encountered in the structure of antibiotic or antitumor drugs. An easy synthesis of them has revealed itself necessary in order to elucidate the mechanism of action of these naturally occurring substances. A method of preparation of conjugated b-ethylenic thiazole[3,2-b] [1,2,4]triazoles by heating a 3-thio substituted [1,2,4]triazole in the presence of polyphosphoric acid is reported here, giving the
在抗生素或抗肿瘤药物的结构中经常遇到噻唑环。为了阐明这些天然存在的物质的作用机理,对它们的简单合成已显示出其自身的必要性。此处报道了一种通过在多磷酸存在下加热3-硫代取代的[1,2,4]三唑来制备共轭β-亚乙基噻唑[3,2- b ] [1,2,4]三唑的方法,得到预期产品的产率为60%。
