Abstract An empirical method was developed to determine the absoluteconfiguration of monosaccharides, based on high-field 1H NMR spectroscopy of their per- O-(S)-2-methylbutyrate (SMB) derivatives. The SMB derivatives of the D and L forms of a given monosaccharide are diastereomers, allowing them to be distinguished on the basis of differences in their 1H NMR chemical shifts.
