NOVEL PREPARING METHOD FOR NOJIRIMYCIN AND ITS RELATED COMPOUND

摘要

The present invention relates to an efficient new route for the preparation of (+)-nojirimycin and (+)-1-deoxynojirimycin which involves the steroselective reductive amination of 1,2-O-isopropylidene-5-oxo- alpha -D-glucuronolactone. The reductive amination uses particular oximes of the 5-oxo compound.
