Popis: Glycosylation of 2-O-acyl fructopyranosides was investigated, which were shown to be effective glycosyl donors for d -fructopyranoside synthesis with good β-selectivity and yields. For bulky acceptor 4e, α-anomer 5e was obtained with α/β = 65:23. Unexpected ring-opening was observed during acetylation of 9, indicating the sensitivity of the fructopyranosyl ring.
