N-Acyliminium Ion Rearrangements: Generalities and Application to the Synthesis of Pyrrolizidine Alkaloids

N-Acyliminium ions of the 2-aza-1,5-hexadienyl type frequently rearrange to isomeric ions by a process which is formally a 2-aza-Cope rearrangement.When gem-dimethyl substitution is present at C-4 of the initially formed N-acyliminium ion, the rearranged

REARRANGEMENTS OF N-ACYL-2-AZA-1,5-HEXADIENES: APPLICATION TO SYNTHESES OF TRAECHELANTHAMIDINE AND SUPINIDINE

Efficient syntheses of the pyrrolizidine bases traechelanthamidine (4) and supinidine (5) via an N-acyliminium ion rearrangement-cyclization are described.
