Channel‐Type Molecular Structures. Part 2. Synthesis of Bouquet‐Shaped Molecules Based on a β‐Cyclodextrin Core

A new series of channel‐type molecules presenting the features of potential transmembrane structures is described. They result from the grafting of amphiphilic side chains on a β‐cyclodextrin derivative 3 that constitutes the organizing core. They belong to the ‘bouquet’ family (B). Compounds bearing poly(oxyethylene) side chains, B 16 and 17, and their polymethylene analogues B 18 and 19, were synthesized. The properties investigated emphasize the suitability of such molecules to be incorporated into lipid bilayer membranes.
