A fruit chitosan, intermediate, preparation method and use thereof

The invention discloses a fructan, and an intermediate, a preparation method and an application thereof. The preparation method of the fructan I comprises the steps: in an organic solvent, and under the action of an alkaline reagent, carrying out a deprot

Synthesis of oligo-fructopyranoside with difructopyranosyl N-phenyltrifluoroacetimidate donor

The hexa-fructopyranoside was synthesized with N-phenyltrifluoroacetimidate glycosylation. The synthesis was achieved by regioselective glycosylation on the 1-OH of fructopyranosyl acceptor. Fructosyl oligosaccharides were elongated with β-(2 → 1)-difructopyranosyl unit in every two steps, without any further protection/deprotection step. This work proved N-phenyltrifluoroacetimidate glycosylation a practical method for oligo-fructopyranoside synthesis.

Synthesis of d-fructopyranosides with 2-O-acyl-β-d-fructopyranosides

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.

Anomeric spiroepoxides derived from fructopyranose, and the synthesis of new fructophosphonic acids

The synthesis of D-fructose 1-deoxy 1-phosphonic acid (2) is described utilising the reaction of diethyl trimethylsilyl phosphite with a novel spiro anomeric epoxide, derived from fructose.

DISTRIBUTION OF TAUTOMERS IN ACYLATED KETOSES. AN IMPORTANT FACTOR IN KETOSIDE SYNTHESIS

Formation of tautomers upon acylation of D-fructose and several 1-O-substituted derivatives thereof is studied and appropiate intermediates are used in stereoselective glycoside synthesis.
