toward a variety of several α-halo- carbonyl compounds was investigated. Thus, reaction of 1 with α-bromoketones, hydrazonoyl bromides, and 2-chloro-N-arylacetamides afforded the corresponding dihydrothiazole, 1,3,4-thiadiazole, and thiophene derivatives, respectively. The synthesis of thiazolidin-4-one 11, thiazolidin-5-one 12, and some azo derivatives of thiazolidin-5-one were described. 5-Arylazothiazoles
研究了 2-苯基硫代氨基甲酰乙酸乙酯 1 对多种 α-卤代羰基化合物的行为。因此,1 与 α-溴酮、腙酰溴和 2-氯-N-芳基乙酰胺反应分别得到相应的二氢噻唑、1,3,4-噻二唑和噻吩衍生物。描述了 thiazolidin-4-one 11、thiazolidin-5-one 12 和 thiazolidin-5-one 的一些偶氮衍生物的合成。5-芳基偶氮噻唑 17 和 19 是通过腙酰溴 3 与不同硫脲衍生物的缩合反应合成的。© 2006 Wiley Periodicals, Inc. 杂原子化学 17:299–305, 2006; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20206
