The step-by-step analysis of high-resolution proton and 13C NMR spectra of per-O-methylated-6-monoamino and 6,6-diamino-A,D-β-cyclodextrins is described. Selected 2-D experiments (COSY, NOESY, HSQC, DEPT, and HMBC) allowed us to challenge the current interpretation. The full assignment of the proton and carbon-13 NMR spectra of these two compounds was performed enabling us to complete the assignment of NMR spectra acquired at 500 and 800 MHz for these important synthetic intermediates.Key words: COSY, NOESY, HSQC, DEPT, HMBC, NMR, 6-amino-β-cyclodextrins, 6,6-diamino-β-cyclodextrins.
