Synthesis of a new aza crown ether (23-crown-7) or (21-crown-7)

is a continuing interest in the synthesis of aza-crown compounds. The aza-crowns exation properties that are intermediate between those of the all-oxgen crowns which st ex alkali and alkaline earth metal ions, and those of the all-nitrogen cyclams, which st ex heavy-metal cations. These mixed complexation properties make the aza-crowns interes c hers in many areas such as atomic energy, medical and pharmacy, environmental, biology ver, they are very expensive owing to their difficult synthesis, tedious purification and, i very low yield [2]. research work, we want, to prepare a new macrocycle as crown compounds, by reaction ne tetra amine with [(4-methyle)-(o-methyle-oxiran) phenyl] 2, 2’ sulfoxide, which have onalized with OH group in their rings. s purpose, bis [(4- methyl) phenol] 2, 2 -sulfoxide prepared, then it was reacted with allyl bromi uoro per benzoic acid for preparing of bis [(o-methyl oxiran) p-cresyl] 2, 2́- sulfoxid. After tha ne tetra amine was reacted with bis [(o-methyl oxiran) p-cresyl] 2, 2́- sulfoxid and its produce be7) or (21-C-7) under region of impugnation. The structures of these new macrocycles have spectral date in cluding IR, 1H NMR and 13CNMR
