Synthesis and metal complexes of symmetrically N-substituted bispidinones

Abstract The symmetrically substituted bispidinones (9–23) were prepared by the Mannich reaction. The bispidinone (28) can be used to generate the diaminoethyl derivative (25) and the diphenoxy ether (32). The crystal structure of the glycinic bispidinone (20) is reported. Metal complexes of bispidinones (4), (35–54) were prepared with copper, palladium and platinum.
