Synthesis and Characterization of Tetrachloro-1,3-Oxazepine Derivatives and Evaluation of their Biological Activities

{{output}}
6,7,8,9-Tetrachloro[1,3]oxazepine-1,5-dione derivatives 1b-10b have been synthesized by reacting Schiff bases 1a-10a with tetrachlorophthalic anhydride (TCPA) under (2 + 5 ∆ 7) cycloaddition reaction conditons. All reactions had been monitored using TLC. FT I... ...
