Synthesis of ornithine lactams via diastereoselective photocyclization of 2-amino-4-oxo-4-phenyl-butanoyl amines

The diastereoselective synthesis of ornithine lactams 6-9 via photoinduced ε-hydrogen ion followed by cyclization of the corresponding 1,6-biradicals is described. A highly asymmetric 1,4-induction is observed.
