摘要:
Provided is a method for preparing 3-O-benzyl-1,2-O-isopropylidene-α-L-idofuranose, which comprises: (1) protecting hydroxyl of 3-O-benzyl-1,2-O-isopropylidene-α-D-glucofuranose (III) by benzoyl and methylsulfonyl to obtain 6-O-benzoyl-3-O-benzyl-1,2-O-isopropylidene-5-O-methylsulfonyl-α-D-glucofuranose (V); (2) subjecting compound (V) to a cyclization reaction under an alkaline condition to obtain 5,6-epoxy-3-O-benzyl-1,2-O-isopropylidene-α-L-idofuranose (VI); and (3) subjecting compound (VI) to a ring-opening reaction to obtain 3-O-benzyl-1,2-O-isopropylidene-α-L-idofuranose.
