Determination and configuration of N ‐glycosyl‐3‐carbamoylpyridinium ions. A correction . The work reported twenty years ago by one of us ( M. V. ) [2] has been reproduced and enlarged. In our previous communication we describe how the kinetics of the periodic oxidation of an anomeric pair of nucleosides would allow to assume the configuration and the conformation of the sugar part of the molecule, but our hypothesis was not confirmed by the 1 H‐NMR. spectroscopy. In the present work we show that our point of view was and is definitively exact, but that N ‐α‐ and N ‐(β‐ D ‐glucosyl)‐3‐carbamoyl‐pyridinium‐ion have been involuntary confounded in the former publication.
