Synthesis of New Rhodanine, Thiazole, Quinazolin-4-One, Imidazolone and Pyranothiazole Derivatives Incorporating Antipyrine Moiety as Antimicrobial Agents

Abstract: A new series of heterocycles incorporating antipyrine moiety were synthesized via reactions of 4-aminoantipyrine 1 with carbon disulphide then alkylation and /or chloroacetic acid to produce dithiocarbamate and rhodanine 3, 4 and 9. Multi-component reaction (MCR) of 4-aminoantipyrine with carbon disulfide and DMAD afforded rhodanine 7. The interaction of 9 with diazonium salt, DMF-DMA, nitrous acid and aromatic aldehydes to give thiazolidinone derivatives 10, 11, 13 and 14, respectively. Pyranothiazole 16 was … Show more
