Deoxymannojirimycin [1,5-dideoxy-1,5-imino-D-mannitol] may be prepared in moderate amounts in an overall yield of 35% in ten steps from diacetone glucose; the key step is formation of the piperidine ring by intramolecular nucleophilic displacement of a triflate at C-2 of a methyl glucofuranoside by a nitrogen function at C-6, irrespective of the anomeric configuration of the sugar.
