Unbranched, and α- and β-methyl-branched, trihydroxypiperidineα-iminonitriles have been obtained in a single step from protected 5-O-tosylate pentoses. This reaction comprises a one-pottandemStreckerreaction and iminocyclisation. These trihydroxypiperidineα-iminonitriles are precursors to trihydroxypipecolic acids. No formation of pyrrolidine products was observed.
