More Information
Summary:There is provided an efficient and excellent preparation method of an ±-halo-tetraacyl-glucose which is suitable for industrial preparation, which comprises reacting D-glucose or lower alkyl D-glucoside with a reactive derivative of a carboxylic acid and a metal halide to prepare the ±-halo-tetraacyl-glucose represented by the formula (III): wherein R represents an optionally substituted lower alkyl group or an optionally substituted aryl group, and X represents a halogen atom, in one step, and the resulting ±-halo-tetraacyl-glucose (III) can be converted into a compound of the formula (I) or a salt thereof by subjecting to a conventional method.
