Abstract

Abstract Several monofunctionalized triaza-crowns and cyclams each containing a secondary amine group on a side chain have been prepared in good yields in few steps from readily available starting materials. The X-ray crystal structure of the complex of silver ion with 1-(2-ethylamino) ethyl-4, 7, 10, 13-tetraethyl-1, 4, 7, 10, 13- pentaazacyclopentadecane (4) shows that the nitrogen atom of the side chain interacts ...
