6,7,9,10-Tetra-hydro-16,22-ethano-oxyethano-5,8,11,19-tetra-oxa-16,22-diaza-dibenzo[h,q]cyclo-octa-decine-17,21-dione: a benzyl-annelated macrobicyclic diamide.

ABSTRACT: The macrobicyclic title compound, C(24)H(28)N(2)O(7), has two tertiary diamide bridgehead atoms and is composed of a 12-membered ring (N(2)O(2) donor set) and two 18-membered rings (N(2)O(4) donor sets). The solid-state structure shows that each of the amide groups is not coplanar with the adjacent benzene ring and NMR studies indicate that this conformational relationship persists in solution.

Project description:The absolute configuration of the title compound, C(18)H(24)O(5)·H(2)O, was not been determined by anomalous-dispersion effects, but has been assigned by reference to an unchanging chiral centre in the synthetic procedure. Intra-molecular O-H?O hydrogen bonds stabilize the mol-ecular conformation. In the crystal, O-H?O hydrogen bonds link the main mol-ecules and the water mol-ecules, forming an infinite three-dimensional network.

The bridging subunits, together with the short bridging strand (NCCOCCN) from each monocycle, define a 24-membered ring (N(4)O(4) donor atom set) that forms a central cavity.

Project description:In the title salt, C12H28N2O4 (2+)·2C5H4NO2 (-), the 1,4,10,13-tetra-oxa-7,16-di-aza-cyclo-octa-decane dication possesses inversion symmetry.
