Abstract:  Furylidene acetals of methyl glycopyranosides and glycofuranosides have been studied by low and high resolution mass spectrometry. Differences in the fragmentation of compounds substituted at various positions with the furylidene residue and deuteration of substances wTith free hydroxyl groups permitted elucidation of the mechanisms of the fragmentation and of the formation of structurally significant ions. Using the established fragmentation patterns the structures of some products of condensation of 2-furaldehyde with D-glucose and D-xylose, formed under the conditions of the formation of 2-furaldehyde itself, have been determined.
