Synthesis of potassium (2R)-2-O-α-d-glucopyranosyl-(1→6)-α-d-glucopyranosyl-2,3-dihydroxypropanoate a natural compatible solute

Ethyl 6-O-acetyl-2,3,4-tribenzyl-1-thio-d-glucopyranoside, as a mixture of anomers, was employed for the stereoselective synthesis of the potassium salt of (2R)-2-O-α-d-glucopyranosyl-(1→6)-α-d-glucopyranosyl-2,3-dihydroxypropanoic acid (α-d-glucosyl-(1→6

Acetonyltriphenylphosphonium bromide (ATPB): A versatile reagent for the acylation of alcohols, phenols, thiols and amines and for 1,1-diacylation of aldehydes under solvent-free conditions

A wide variety of alcohols, phenols, amines and thiols may easily be converted into the corresponding acetate derivatives by treatment with acetic anhydride (1.5-2.0 equivalents) in the presence of acetonyltriphenylphosphonium bromide (ATPB; 5 mol %) in good yields at room temperature. With the same precatalyst, both aliphatic and aromatic aldehydes can also be transformed into the corresponding gemdiacetates under reflux conditions.

SYNTHESIS OF THE TETRASACCHARIDE REPEATING-UNIT OF THE POLYSACCHARIDE FROM Klebsiella TYPE 23

Methyl 2-O-allyl-4-O-benzyl-3-O-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-α-L-rhamnopyranoside was obtained by condensing methyl 2-O-allyl-4-O-benzyl-α-L-rhamnopyranoside with tetra-O-acetyl-α-D-glucopyranosyl bromide.Benzylation, removal of the allyl g
