  Novel benzene-bridged macrobi- and macrotricyclic polyethers

  摘要：

  Novel three-dimensional benzene-bridged macrobicyclic polyether 1 and macrotricyclic polyether 2 have been prepared. Macrobicyclic triply bridged cyclophane crown compound 1 was synthesized by a tripode-tripode coupling of 1,3,5-tris[7'-(tosyloxy)-2',5'-dioxa-1'-heptyl]benzene (19) with 1,3,5-tris(hydroxymethyl)benzene (5). Macrotricyclic quadruply bridged cyclophane crown ether 2 was obtained by a quadrupode-quadrupode coupling of 1,2,4,5-tetrakis(7'-tosyloxy-2,5'-dioxa-1'-heptyl)benzene (20) with 1,2,4,5-tetrakis(hydroxymethyl)benzene (6). These ligands could have suitable rigidity and cavity sizes for the coordination of metal cations. They appear to have selectivities for cesium over sodium and lead ions, and 2 shows a log K value of 3.50 for interaction with cesium ion in 80% CH3OH/20% water (v/v). Macrotricyclic polyether 2 containing benzene bridgeheads is a new type of ligand, and its structure was confirmed by an X-ray crystallographic study.
