2‐Cyano‐N‐(thiophen‐2‐yl)acetamide in Heterocyclic Synthesis: Synthesis and Antibacterial Screening of Novel Pyrido[1,2‐a]thieno[3,2‐e]pyrimidine‐2‐carboxylate Moieties

A novel series of interesting 6,8‐dicyanopyrido[1,2‐a]thieno[3,2‐e]pyrimidine‐2‐carboxylate compounds were prepared via the reaction of readily accessible 2‐cyano‐N‐(thiophen‐2‐yl)acetamide with arylidene malononitriles in pyridine in the presence of piperidine. Biological screening of the tested compounds as antibacterial agents was also studied.
