Selective mono- and bis-condensations of isophthalaldehyde derivative with 6-(o-aminoanilino)cyclodextrins

Abstract

Selective mono- and bis-condensations of an isophthalaldehyde derivative with a stoichiometric amount of 6-(o-aminoanilino)-α- (or β-) cyclodextrin to afford 2-(formylphenyl)benzimidazole-pendant α- (or β-) cyclodextrin and bisbenzimidazole-bridged homo- or hetero-dimers of cyclodextrins are described.
