ChemInform Abstract: Synthesis of Diepoxides and Diaziridines, Precursors of Enantiomerically Pure α‐Hydroxy‐ and α‐Amino Aldehydes or Acids, from D‐Mannitol.

D‐Mannitol (I) yields the monoacetonides (II) and (III) which are converted to the chiral diepoxides (IV) and (VI) and to the optically active diaziridines (VII) and (VIII).
