Abstract
A series estrogen-imidazolium cyclophanes have been synthesized for the first time by direct quaternization of 2,4-bis(N-imidazolylmethyl)estrogens and corresponding dibromides in highly diluted acetonitrile solution in excellent yields. All new compounds were characterized by MS, 'HNMR and elemental analysis.Keywords
