In this study some new compounds have been synthesized including preparation of some different Schiff  bases[1-6] from the reaction benzdine with substituted of benzal-dehyde in absolute ethanol and converted into derivatives of 1,3-oxazpines(by ring clo- sure reaction (2+5) of Schiff bases with maleic anhydride in dry benzene[7-12],also the 2,3 –dihyroquinozoline-4(1H) one[13-17] were prepared. The prepared compounds were characterized by color and melting point determination, FT-IR and UV-Vis spectral  analysis . Some of the prepared compounds were identified by 1H- NMR and C.H.N spectra  analysis .
