A concise and straightforward synthesis of two amino-DNJ derivatives, 6-amino-6-deoxy-DNJ and 6-amino-1,6-dideoxy-l-talonojirimycin is described from a commercial and cheap starting material. The methodology employed takes advantage of diastereoselective reductive amination to achieve the two non-natural iminosugars in three and five steps, respectively.
