Some novel thiophenes (4a,b, 5, and 9a,b) were obtained from the cycloalkylation of the thiocarbamoyl group in the cyanothioacetanilide derivative (1) with α-halocarbonyl compounds. Also, the reaction of cyanothioacetanilide derivative with phenyl isothiocyanate in the presence of potassium hydroxide followed by in situ heterocyclization of the resulting adduct with α-halocarbonyl compounds furnished
一些新型噻吩(4a,b, 5 和 9a,b)是由氰硫代乙酰苯胺衍生物 (1) 中的硫代氨基甲酰基与 α-卤代羰基化合物环烷基化得到的。此外,氰基硫代乙酰苯胺衍生物在氢氧化钾存在下与异硫氰酸苯酯反应,然后将所得加合物与 α-卤代羰基化合物原位杂环化,得到相应的噻唑(12、14和15)、吡唑(19)和吡唑啉[1,5-a]嘧啶(22、25和26)衍生物。测试化合物(4b、5、9a、12、13、18、22、25和26)以评估它们的抗微生物活性。补充材料可用于本文。转至出版商在线版的磷、硫和硅及相关元素,查看免费的补充文件。
