Synthese und 1H‐NMR‐Studie der vier unverzweigten peracetylierten β‐ D ‐Glucopyranosyl‐β‐gentiobiosen

Synthesis and 1H‐NMR Study of the Four Unbranched Peracetyl‐β‐D‐glucopyranosyl‐β‐gentiobioses With regard to the structure elucidation of an unknown trisaccharide isolated from the stigmas of garden crocusses (Crocus neapolitanus var.), the four unbranched (1→6)‐, (1→4)‐, (1→3)‐, and (1→3)‐, and (1→2)‐connected β‐D‐glucopyranosyl‐β‐gentiobiose peracetates were synthesized. A complete analysis of the 1H‐NMR spectra of the four trisaccharide peracetates was carried out.
