ABSTRACT
A series of new 4-[2-alkyl-2-arylhydrazono]-2-phenyloxazol-5-ones derivatives 2a-d were synthesized by reaction of the oxazolones 1a, b with methyl and ethyl iodides. On the other hand, trial to alkylate 1a with methyl bromoacetate or phenacyl bromide afforded the triazine 3 and pyridinone 7, respectively. The reaction of 2a, b with ammonia or primary aromatic amines or hydrazines gave the acyclic amides 8a, b, 10a-d and hydrazides 12a-d, respectively. Cyclization of 8a, b and 10a, b gave imidazoles 9a, b, and 11a, b. While cyclization of 12a-d afforded triazines 13a, b and 14a, b, respectively
