Dendritic hydrogen bonding receptors: enantiomerically pure dendroclefts for the selective recognition of monosaccharides

Abstract

Enantiomerically pure dendritic cleft receptors (dendroclefts) with a 9,9′-spirobi[9H-fluorene] core are prepared for the recognition of glucopyranosides by H-bonding in CDCl₃; the enantio- and diastereo-selectivities in the complexation processes are modulated by the presence of the dendritic shell.
