Synthesis of Antimicrobial, Amino Pyrano [2, 3-c] Pyrazolone Carbonitrile Derivatives by Thiourea Catalyzed Hetero-Cyclization Reaction
Vijay Pratap Singh, Amrendra Kumar Singh
Abstract: Hetero Diels-Alder reaction for direct [4+2] cycloaddition between vinyl pyrazolone and conjugate amino alkene carbonitrile, catalyzed by thiourea derivatives in DMSO at room temperature gives pyrano[2, 3-c] pyrazolone derivatives. The newly synthesized compounds show antimicrobial activity against Gram positive bacteria (S. aureus and B. subtilis), Gram negative bacteria (P. aeruginosa and E. coli) and antifungal activity against fungi (A. niger).
Keywords: Pyrano [2, 3-c] pyrazole, thiourea derivatives, Hetero cycloaddition reaction, Antimicrobial agent
