NOVEL SYNTHESES OF MONOFUNCTIONALIZED TRIAZA-CROWNS AND CYCLAMS WITH A SECONDARY AMINE GROUP ON A SIDE CHAIN

Article abstract of DOI:10.1016/S0040-4039(00)99152-4

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 strongly with the silver ion.
