Abstract

A simple and convenient method for the preparation of fully acetylated and (3- bromo)benzoylated α-monosaccharides and disaccharides through vigorous mechanical mixing of solid reactants on a high speed shaker is described. Using this technique a variety of α-acylated sugars are prepared, including penta-O-acetyl-α-D-galactopyranose, penta-O- acetyl-α-D-glucopyranose, penta-O-acetyl-α-D-mannopyranose, octa-O-acetyl-α-lactose, penta-O-(3-bromo)benzoyl-α-D-galactopyranose, penta-O-(3-bromo)benzoyl-α-D-gluco- pyranose, penta-O-(3-bromo)benzoyl-α-D-mannopyranose, and octa-O-(3-bromo)benzoyl- α-lactose.
Keywords: α-Galactose; α-glucose; α-mannose; lactose; mechanochemical mixing α-Galactose; α-glucose; α-mannose; lactose; mechanochemical mixing
