Title:
フラノース誘導体の製造方法
Document Type and Number:
Japanese Patent JP5550234
Kind Code:
B2
Abstract:
An object of the present invention is to provide a industrially appropriate method for producing the ²-anomers of ribofuranose derivatives in a highly selective manner at a high yield. The present invention provides a method for producing ribofuranose derivatives wherein ²-anomers is precipitated from among the generated furanose derivatives by controlling the amount of a reaction reagent used and/or using a poor solvent in the acetolysis reactions of 2,3,5-tri-O-acyl-1-O-alkyl-ribofuranose and 2,3-di-O-acyl-1-O-alkyl-5-deoxy-ribofuranose.
