Synthesis And Identification Of from HEMA Schiff Base Derivatives Contains Aldehyde Group For Hexa and Hepta Cyclization

In this research the polymer which contains aldehyde group [H1] has been prepared by oxidation [H] using oxidizing agent (Dess Martin Periodinane), dialyzed ethanol, Schiff bases[H2,H5andH8] compounds have through reaction of compound with appropriate amines, [H3] hydroquinazolin ring [H2] 2-amino benzoic acid.[H4]which cyclization phthalic anhydride. [H6,H7]were [H5] acid and anhydriede. Reaction comp[H1] 4-amino benzaldehyde afforded comp[8]. The [H9] [H8] thiocarbohydrazide, structures synthesized [1-9] characterized avaible spectral ( IR, 1H-NMR) methods result obtained improved assigned to these
