A new, reliable method for the introduction of an amine group at positions 2 or 6 of beta-cyclodextrin and permethyl-beta-cyclodextrin is described. It involves selective tosylation followed by azide substitution and almost quantitative reduction with triphenylphosphine followed by hydrolysis of the phosphinimine intermediate.
