Selective deacetylation reactions of the peracetylated reducing disaccharides (1), (5), (9), (15), beta-D-glucopyranose (17) and 2-acetamido-2-deoxy-beta-D-glucopyranose (19), with 1-2 equiv. of hydrazine hydrate in acetonitrile, gave predominantly the corresponding heptaacetates (2), (6), (10), (16), the tetraacetate (18) and the triacetate (20), with the free hydroxy group at C1. Reaction of (1) with 1-2 equiv. of hydrassine hydrate in N,N-dimethylformamide also afforded the heptaacetate (2), but in lower yield. When reactions of (1), (5) and (9) were performed with 2-5 equiv. of hydrazine hydrate, deacetylation also occurred at other positions to afford the corresponding hexaacetates (3), (7), (11) and (12), with hydroxy groups at C 1,2 or C 1,3, and the pentaacetates (4), (8) and (13), with hydroxy groups at C 1,2,3. Maltose octaacetate (9). in addition, yielded the tetraacetate (14) in which the free hydroxy groups were located at C1,2,2?,3. Compound (15) on treatment with 2-5 equiv. of hydrazine hydrate afforded an intractable mixture. The reaction of methyl 2,3,4,6-tetra-O-acetyl-alpha-D-glucopyranoside (21) with 2-5 equiv. of hydrazine hydrate gave the 3,4,6-triacetate (22), a mixture of the 2,6- and the 3,6-diacetates (23) and (24), respectively, the 4,6-diacetate (25), and the 6-acetate (26).

A series of glycosyl hemiacetal derivatives have been transformed into thioglycosides and glycosyl thiols in a one-pot two-step reaction sequence mediated by Appel reagent (carbon tetrabromide and triphenylphosphine). 1,2-trans-Thioglycosides and beta-glycosyl thiol derivatives were stereoselectively formed by the reaction of the in situ generated glycosyl bromides with thiols and sodium carbonotrithioate. The reaction conditions are reasonably simple and yields were very good.

Synthetic Route of 10343-06-3, An article , which mentions 10343-06-3, molecular formula is C14H20O10. The compound – 2,3,4,6-Tetra-o-acetyl-D-glucopyranose played an important role in people’s production and life.

The 2,3,4,6-tetra-O-benzyl-1-O-(N-benzyloxycarbonyltripeptidyl)-D-glucopyranoses 1, 8, and 13 were synthesised from 2,3,4,6-tetra-O-benzyl-alpha-D-glucopyranose and the active esters of the appropriate N-protected tripeptides (Gly-Gly-Gly-, L-Phe-Gly-Gly-, and Gly-Gly-L-Phe-) in the presence of imidazole; the anomeric mixtures were resolved and the alpha and beta anomers characterised.The beta anomer of 13, containing the L and D enantiomers (ratio ca. 3:1) of Gly-Gly-Phe- as the aglycon, could be resolved by column chromatography into the pure isomeric forms.Catalytic hydrogenolysis of the beta anomers, in the presence and absence of a strong acid, yielded the free 1-esters 2beta, 9beta, and 14beta, which were characterised as the mono-oxalate or trifluoroacetate salts and as free bases.Similarly, the alpha anomers afforded 2alpha, 9alpha, and 14alpha, whereas omission of the strong acid led to accompanying 1 –> 2 acyl migration, to give the 2-O-acyl derivatives.All of the compounds prepared were converted into the N-acetyl and/or peracetylated derivatives.The 1-esters 2beta and 9beta, both in the charged and uncharged form, and the trifluoroacetate salt of 14beta, are susceptible to cleavage by beta-D-glucosidase; the enzyme had no effect on the uncharged form of 14beta.This difference between 14beta and its salt is discussed in conformational terms.
