Notes:
Derivatives of 1,6-anhydro-2,3-O-isopropylidene-β-D-talopyranose (I) specifically deuterated at C-3 (II), at C-4 (III), at C-3 and C-4 (IV), and in the isopropylidene group (V) have been examined by high-resolution, electron-impact mass spectrometry. From the elemental compositions of the fragment ions, the mass-number shifts upon deuterium incorporation, and analysis of metastable transitions, it was possible to identify the origin of the hydrogen atoms in all fragments formed from I and to present a complete scheme of fragmentation pathways undergone by this molecule.
