| ETEREOSPECIFIC SYNTHESIS OF α-D-FRUCTOFURANOSIDES——SYNTHESIS OF THE OLIGO-FRUCTAN DIASTEREOISOMERS | |
| 摘 要： | α-fructofuranosides were stereospecifically synthesized from2-O-Ac-1,3,4,6-O-tetra-benzoylfructose by employing TMSOTf as a catalyst.Meanwhile,one diastereoisomer derivative of sucrose and two of fructanoligomers were synthesized.The structure of all products were confirmed by~(13)C-NMR and ~1H-NMR spectra. |
