Abstract Chloroacetylation of alkyl glycopyranosides of β-D-galactose, β-D-glucose and α-D- mannose as well as of free D-glucose, D-galactose, D-mannose and D-xylose, using chloroacetic anhydride as acylating reagent, gave the corresponding fully chloroacetylated pyranose derivatives in excellent yields. From D-glucose, 1, 2, 3, 6-tetra-O-chloroacetyl-α-D- glucopyranose (9) was also obtained. Subsequent treatment of the fully chloroacetylated α ...
