Using click chemistry to access mono- and ditopic β-cyclodextrin hosts substituted by chiral amino acids

A wide range of chiral mono- and ditopic cyclodextrin-based receptors have been synthesized by CuI-catalyzed azide–alkyne cycloaddition starting from mono-6-azido-β-cyclodextrin and chiral amino acids. Of interest, microwaves proved very efficient to access a wide range of ditopic β-cyclodextrin receptors with quantitative yields.
