Abstract
Some new β -lactam, thiazolidinone derivatives were synthesized by reaction of new Schiff bases with compounds 4 and oxazoles, pyrazoles, pyrimidines, and pyrimidinethion were also synthesized by reaction of an arylidino system with hydroxyl amine hydrochloride, hydrazines, urea, and thiourea, which we expected to have biological activities such as bactericidal and fungicidal or other applications of certain interest.
