| Abstract | ||
| New 1,3-oxazepine and 1,3-diazepine derivatives containing azo group have been prepared. The first step,(O-tolidine) was converted to [3,3`-dimethyl-(1,1`-biphenyl) -4,4`-diyl) bis (diazene-1,2-diyl))bis(naphthalene-2- amine)] Azo O-tolidine[A].by Azotization reaction with naphthyl amine. The second step, amine group of the azo derivative [A] was condensed with different aromatic aldehydes[p-dimethyleaminobenzaldehyde, 4-chlrobenzaldehyde,4-nitrobenzaldehyde,4-bromo benzal dehyde , 4-hydroxy-3-methoxybenzaldehyde] in the presence of absolute ethanol to give new azo Schiff bases derivatives [B-F] respectively. Then, the resulting imines derivatives [B-F] were reacted with maleic anhydride and phathalic anhydride in dry benzene to give new 1,3-oxazepine-4,7-dione ring derivatives [Ba-Fa] , [Bb-Fb] , all these compound reaction with sulphadiazene to producte 1,3-diazepine-4,7-dione ring derivatives [Ba1-Fb2]. Also study the Biological activity to this derivatives ; All prepared compounds were characterized by melting points and FT.IR spectroscopy, some of them are characterized by 1H-NMR spectroscopy and C.H.N analysis. | ||
