ethyl saccharinylcyanoacetate derivative with a variety of active methylene reagents and nitrogen nucleophiles afforded novel series of polyfunctionally substituted heteroaromatic derivatives 5–13, respectively. The pyrazole derivative was seemed to be the excellent precursors for the synthesis of pyrazolo[1,5-a]pyrimidine derivatives 14–24. The antimicrobial screening of some synthesized products was evaluated
