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

Synthesis and 1 H‐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 1 H‐NMR spectra of the four trisaccharide peracetates was carried out.
