TY - JOUR ID - TI - Synthesis and spectroscopic studies of some new oxazepine derivatives throughout [2+5] cycloaddition reactions (IV) AU - Alaa J.Mahrath AU - Saadon A. Aowda AU - Sabah N Kamil PY - 2012 VL - 22 IS - 1 SP - 377 EP - 392 JO - Journal of University of Babylon مجلة جامعة بابل SN - 19920652 23128135 AB - The present work included Condensation reactions of O-tolidine with different aromatic aldehyde in absolute ethanol to give Schiff bases (w13-w16 )in high yield which on reaction with maleic and phthalic anhydride by [2+5] cycloaddition reactions in presence of suitable solvents give the corresponding [1,3]oxazepine -4,7-dione (w13m-w16m ) and [1,3] oxazepine -1,5-dione (w13ph –w16ph) respectively. The structure of new synthesized compounds were monitored by T.L.C and established on the basis of elemental analysis , FT-IR and 1H-NMR.
