Abstract
One pot procedure for the synthesis of 8-amino-3-oxoindolizidines from Z δ-protected ornithyl ketomethylene pseudodipeptide derivatives is described. This procedure, involving hydrogenolysis of the Z-group, intramolecular reductive amination and γ-lactamization, provides readily access to a variety of 3-oxoindolizidines of defined stereochemistry at C-8 and C-8a.
