Abstract

Vicinal spin–spin coupling constants frequently used for conformation analysis were determined for ammonium-containing 13C–N–C–1H systems by using HMBC. 1-Deoxynojirimycin hydrochloride provided an appropriate system for measuring the antiperiplanar and gauche interactions, which were determined to be 7.3 and 1.6 Hz, respectively.
