An Alternative Synthesis of Cyclic Aza Compounds
Boerjesson, L.,Welch, C. J.
, p. 621 - 626 (2007/10/02)
A series of cyclic mono-, di- and poly-aza compounds has been synthesised in moderate to good yields by reaction of p-toluenesulfonamide and either α,ω-ditosylates or α,ω-dichlorides.

Synthetic routes to the macrocyclic polyamine derivatives (1) and (3) are described, together with an investigation of the complexing properties of the triamines (1d) and (3d) with primary alkylammonium cations.Macrotricyclic and macrotetracyclic compounds may be obtained from the macrocycle (1) by a stepwise procedure whereas macrocycle (3b) can be converted into a macrotricyclic derivative in a one step alkylation procedure.The alkylation of the tetrahydropyrimidone (18) with α,α'-dibromo-m-xylene gives the calix arene analogue (19) which adopts the 'cone' (21a) and '1,3-alternate' (21b) conformations.The macrocyclic hexa-amine (23) may be synthesized by a simple alkylation procedure whereas the octa-amine (27) required a systematic stepwise synthesis.The hexa-amine salt (23)*6 HBr shows selectivity in forming inclusion complexes with the dicarboxylate anions (1-)O2C(CH2)nCO2(1-).
A Convenient Synthesis of 1,3,6-Dioxazocine, 1,3,7-Dioxazocine, 1,3,8-Dioxazecine and 1,3-Dioxa-6,10-diazadodecane

, p. 1327 - 1330 (2007/10/02)
A series of perhydro heterocycles of eight to ten ring members containing one nitrogen and two oxygen atoms has been prepared.These include four 1,3,6-dioxazocines, and 1,3,7-dioxazonine and one 1,3,8-dioxazecine.A twelve-membered ring containing two oxygen and two nitrogen atoms was also prepared.An X-ray structure of one of the 1,3,6-dioxazocines, 5, was determined.This compound crystallized in the orthorhomic space group Pccn with a = 25.922(15) Angstroem, b = 12.150(4) Angstroem and C = 9.342(4) Angstroem.Two of the 1,3,6-dioxazocines have the benzylidine acetal structure which will hydrolyze to give benzaldehyde.
SYNTHESIS OF 2,3,5,6-TETRAHYDRO-1H,4H,11cH-3a,6a,11b-TRIAZABENZANTHRACENE (5) AND X-RAY CRYSTAL STRUCTURE DETERMINATIONS OF (5), HEXAHYDRO-1H,4H,7H,9bH-3a,6a,9a-TRIAZAPHENALENE (1), BENZO-1,5,9-TRIAZADODECANE N,N',N''-TRITOSYLAMIDE, AND OF 1,5,9-TRIAZADODECANE N,N'N''-TRITOSYLAMID

The synthesis of 2,3,5,6-tetrahydro-1H,4H,11cH-3a,6a,11b-triazabenzanthracene (5) is described.X-ray crystal structure determinations on hexahydro-1H,4H,7H,9bH-3a,6a,9a-triazaphenalene (1) and its benzoanaloque (5) show them to adopt differing conformations; the reasons for this are discussed.
Macrocyclic polyamines
-
, (2008/06/13)
Macrocyclic polyamines containing 3-7 nitrogen atoms in the ring and destablized to complex formation by (1) an asymmetric ring and/or (2) provision of nitrogen atoms in excess of that required for complex formation are described. The compounds can be used to extract metal ions from solution. The metal complexes are thermally activated curing agents for epoxy resins.
