The proton and carbon nuclear magnetic resonance (NMR) resonances have been assigned for 3A-amino-3A-deoxy-(2AS,3AS)-α-, β- and γ-cyclodextrins (CyDs) (3α, 3β and 3γ). In these CyDs, a glucose residue has been replaced by an altro-pyranose unit with an axial hydroxyl group. Assignments were made with one-dimensional NMR and COSY, TOCSY, ROESY and CHSHF (heteronuclear shift correlation) spectra. Titration by NMR shift changes gave amino-group pKa values of 7.73 and 8.84 for 3β and 6A-amino-6A-deoxy-β-CyD (6β), respectively.
