摘要:3-Amino-5-(4-chlorophenylamino)-4-cyanofuran-2-carboxamide (2) was used as the key molecule for preparation of various furopyrimidines 3-9 and formation of spiro-cycloalkane furopyrimidines 10,11.Also,poly fused heterocyclic compounds 13-17 were prepared from compound 2.The synthesized compounds were screened for their antimicrobial activity.
