Abstract A series of N-hydroxymethylamides, RCONR′ CH 2 OH, and their O-methyl and O- acetyl derivatives, have been studied by 13 C and 1 H magnetic resonance spectroscopy. Signals have been assigned to the E-and Z-isomers on the basis of the analysis of the fully coupled spectra, and by comparison of the chemical shifts with those of model compounds. The introduction of the hydroxy, alkoxy or acetoxy groups at the α-position of the N-alkyl ...
