Title:
METHOD FOR PRODUCING Α-HALO-TETRAACYL GLUCOSE
Document Type and Number:
WIPO Patent Application WO/2014/132940
Kind Code:
A1
Abstract:
Provided is a method for producing α-halo-tetraacyl glucose, the efficiency of which is excellent and suited to industrial production. The present invention is a method for producing α-halo-tetraacyl glucose represented by general formula (III) (R represents an optionally substituted lower alkyl group or an optionally substituted aryl, while X represents a halogen atom) in the first stage thereof from D-glucose or a lower alkyl D-glucoside, by reacting a metal halide and a reactive derivative derived from carboxylic acid. In addition, the present invention pertains to a method for producing a compound or salt thereof represented by formula (I) from the obtained α-halo-tetraacyl glucose (III) by using a known method.
