  Studies on 2-Aminothiophenes: Synthesis, Transformations, and Biological Evaluation of Functionally-Substituted Thiophenes and Their Fused Derivatives

  摘要：

  Heterocyclic enamines 1 reacted with ethyl acetoacetate to afford the corresponding amide derivatives 2. Treatment of 2 with carbon disulphide yielded the dipotassium salts 3 which reacted in-situ with a variety of alpha-haloketones to give the respective substititted thiophenes 5, 8, and 13. Die reactivity of the latter products towards various chemical reagents was studied to yield their fused thiophene derivatives 7, 10, 12, and 14, respectively. Some representative compounds were tested for antimicrobial activity.
