Synthesis of Optically Active Heterocyclic Compounds by Preparation of 1,3-Dinitro Derivatives and Enzymatic Enantioselective Desymmetrization of Prochiral Diamines
efficient chemical preparation of novel optically active 2-substituted propane-1,3-diamines is described. Diamines have been obtained from the corresponding commercially available aldehydes in a straightforward two-step synthesis via the corresponding 1,3-dinitro compounds, which were hydrogenated under mild reaction conditions by using platinum dioxide as the catalyst. Subsequent enzymatic enantioselective
