The 1H and 13C NMR spectra of pyridoxine (vitamin B6) and its dibutylstannylene derivative were assigned. Proton detected 1H-13C Heteronuclear Multiple Bond Correlation (1H-13C HMBC) spectroscopy appears to be a necessary tool for the assignment of the quaternary 13C resonances. © 1994, Walter de Gruyter.
