SYNTHESIS OF OXAZIPEN COMPOUNDS VIA SCHIFF BASES
This work involved preparation of cyclic compounds are containing of more than one hetero atoms in their structures like (N)-nitrogen atom. A seven-member ring compounds were prepared by condensation of N,N-di methyl amino benzaldehyde with aromatic amines to give compounds [N2-N17], these compounds were found to react with maleic anhydride to give 7-memberd ring [N18-N32]. All these compounds [N2- N32] were prepared by pericyclic reactions.
