摘要：Five diisopropylidenated monosaccharides, namely 1,2:5,6-di-O-isopropylidene-α-D-glucofuranose, 2,3:5,6-di- O-isopropylidene-α-D-mannofuranose, 1,2:3,4-di-O-isopropylidene-α-D-galactopyranose, 2,3:4,5-di-O-isopropylidene-β- D-fruc-topyranose and 2,3:4,6-di-O-isopropylidene-α-L-sorbofuranose, have been investigated using spectroscopic techniques. These include GC-EI-MS at multiple ionization energies, FTIR, DSC, TG, 1H and 13C NMR, and also DEPT135, COSY, HMQC and HMBC measurements. A high instability towards electronic ionization has been found for this type of compounds.
