摘要

Cationic ring-opening copolymerization of 1

4-anhydro-2

3-O-isopropylidene-α-D-ribo-pyranose (AIRP) with 1

4-anhydro-2

3-di-O-benzyl-α-D-ribopyranose (ADBR) preparedfrom D-ribose was studied. Copolymerization using SbCl5 or BF3 OEt2 as catalyst atlow temperature gave stereoregular (1→4)β-D-ribofuranan (C-1 and C-4 ring cleavagesee Scheme 1) or (1→5) α-D-ribofuranan (C-1 and C-5 ring cleavage) respectively. Theeffects of catalysts

reaction time and temperatures on yield and stereoregularity of the ob-tained polymers were studied.Polymers were charaterized by molecular weight

1H NMR

13C NMR and optical rotation.
