  Abstract A mechanism for the degradation of monosaccharides at room temperature in methyl sulfoxide containing tetrabutylammonium hydroxide has been proposed based on e.s.r. spectroscopic data. Several radicals with semi-dione-like structures were generated during this process, and their hyperfine splittings and g factors have been measured. The mechanism of the reactions was dependent on the chain

  The degradation of a series of deoxy sugars and disaccharides in methyl sulfoxide-tetrabutylammonium hydroxide has been studied by e.s.r. spectroscopy. The generation of radicals and the types of radical formed are dependent on the anomeric configuration of non-reducing moieties and on the positions of the linkages and deoxy groups. Mechanisms for the pathways of degradation are proposed.
