A series of 1-substituent-6-oxo-benzopyridazinones-3-(tetra-O-acetyl-β-D-glucopyranoside) with dextran configuration was synthesized with 1-butyl methylimidazole-4-fluoborate as the reaction media and promoter at room temperature.The products with optical rotation of(+)24.6,(+)11.0,(+)13.6 and(+)20.3 are all dextran.The article studied the influences of reaction time,molar ratio,various ionic liquids and reuse of ionic liquid on the reaction.The structures of the synthesized glycosides were characte-rized by 1H NMR and IR.The method has the advantages of mild condition,few side effects,high yield,environmental benignity,and the ionic liquid can be used again.
