U. Lindemann et al., Synthesis of ornithine lactams via diastereoselective photocyclization of 2-amino-4-oxo-4-phenyl-butanoyl amines, TETRAHEDR-A, 9(24), 1998, pp. 4459-4473
The diastereoselective synthesis of ornithine lactams 6-9 via photoinduced
E-hydrogen abstraction followed by cyclization of the corresponding 1,6-bir
adicals is described. A highly asymmetric 1,4-induction is observed. (C) 19
