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. (English) [ABSTRACT FROM AUTHOR] On décrit l’analyse étape par étape des spectres RMN à haute résolution du 1H et du 13C des 6-monoamino- et 6,6-diamino-A,D-β-cyclodextrines per-O-méthylées. Des expériences bidimensionnelles choisies (COSY, NEOSY, HSQC, DEPT et HMBC) ont permis de mettre en doute l’interprétation actuelle. L’attribution complète des spectres RMN du 1H et du 13C de ces deux produits a été réalisée et elle permet de faire une attribution complète des spectres RMN obtenus à 500 et 800 MHz pour ces importants intermédiaires de synthèse.
