Uses of 1-Cyanoacetyl-4-phenyl-3-thiosemicarbazide in Heterocyclic Synthesis: Synthesis of Thiazole, Coumarin, and Pyridine Derivatives with Antimicrobial and Antifungal Activities
摘要:
The reaction of cyanoacetyl hydrazine with phenylisothiocyanate gave the thiosemicarbazide 3. The latter underwent a series of heterocyclization reactions when it reacts with either aromatic aldehydes or alpha-haloketones, follwed by further reaction of the products with cyanomethylene reagents or hydrazines to give either thiazole, coumarin, or pyridine derivatives. The newly synthesized product showed antimicrobial and antifungal activities.
