Abstract:
© 2017, Springer Science+Business Media, LLC. New pyridoxine derivative with multiple chemical exchanges was studied by 13 C (at 298 K, 188 K) and 2D NMR ( 1 H- 13 C HSQC, 1 H- 13 C HMBC) spectroscopy in acetone-d 6 solution. Complete 13 C NMR data (table with chemical shifts at different temperatures) is presented. Intramolecular mobility of the molecule was analyzed based on the results of 13 C NMR experiments in combination with the data obtained from previous study of this compound by dynamic 1 H NMR spectroscopy.
