Molecular structure and hydrolytic stability amidinium salts derived from triazatricyclo[5.2.1.04,10]decane

Five amidinium salts have been prepared from triazatricyclo[5.2.1.0 4,10]decane (tacnoa) and characterised by mass spectrometry, NMR spectroscopy and X-ray crystallography. The X-ray structures revealed a long distance between the methine carbo

Synthesis of novel derivatives of 1,4,7-triazacyclononane

(equation presented) The coordination environment of 1,4,7-triazacyclononane can be adapted, through sequential functionalization of two secondary amines, to generate ligands applicable in biomimetic studies. Two "amino acids" and an amino derivative have

Selective derivatisation of aza macrocycles

A range of selectively functionalised compounds derived from 1,4,7-triazacyclononane ([9]aneN3), including 4,7-bis(2-hydroxy-2-methylpropyl)-1,4,7-triazacyclononane-1-carbaldehyde (H2L1), 1-benzyl-4,7-bis(2-hydroxy-2-methylpropyl)-1,4,7-triazacyclononane (H2L2) and 1,4-bis(2-hydroxy-2-methylpropyl)-1,4,7-triazacyclononane (H2L3), has been prepared. The structure of H2L3·CHCl3 shows a disordered macrocyclic ring with the major conformer refining to a site occupancy of 0.663(8), and both disordered rings adopting a [333] conformation. The pendant alcohol arms were not disordered and were found to be hydrogen bonded to a CHCl3 solvate molecule with H ... O(1) and H ... O(4) distances of 1.73 and 1.81 A respectively. The structure of Na[Cu(H2L1)(NCMe)][BF4]2[NO 3] shows the copper(II) centre in the [Cu(H2L1)(NCMe)]2+ cation bound to two amine donors and two alcohol donors of H2L1 and to a MeCN molecule. The Cu-N bond lengths lie in the range 1.984(3)-2.015(3) A. Both alcohol donors are protonated, with one short Cu-O(16) bond of 1.963(3) A and one long Cu-O(21) bond of 2.252(3) A. There is also a sixth longer-range interaction of the copper(II) centre with the amide N [N(1)] of H2L1 at a distance of 2.611(5) A, confirmed by the loss of planarity of the C(2)-C(9)-N(1)-C(10)-O(11)-H(10) amide fragment to give a dihedral angle between the planes defined by C(2)-C(9)-N(1) and N(1)-C(10)-O(11)-H(10) of 27.1(4)°. The structure is completed by interaction of O(11) with a Na+ ion which itself bridges to BF4- counter anions leading to a central infinite core of [Na(BF4)2]- aggregates onto which are attached the [Cu(H2L1)(NCMe)]2+ cations. The complex [Cu(H2L2)(OH2)][NO3]2 shows the six-co-ordinate copper(II) centre bound to the three amine and two alcohol donors of H2L2 and to one water molecule. There are four short bonds [to N(7), N(4), O(40) and O(1)] in the range 1.961(5)-2.073(6) A and two longer bonds to N(1) and O(70) at 2.308(5) and 2.313(5) A respectively. The H atoms of the water molecule [O(1)] and one of the pendant arms [O(40)] also make hydrogen-bonding contacts with the nitrate counter ions.

Selective N-Protection of Medium-ring Triamines

Efficient schemes for selective N-protection of 1,4,7-triazacyclononane and 1,5,9-triazacyclododecane and for synthesis of related bis-coronands are based upon the synthetic intermediacy of tricyclic orthoamides.
