Hart, David J.,Yang, Teng-Kuei
, p. 235 - 242 (2007/10/02)
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
Hart, David J.,Yang, Teng-Kuei
, p. 2761 - 2764 (2007/10/02)
Efficient syntheses of the pyrrolizidine bases traechelanthamidine (4) and supinidine (5) via an N-acyliminium ion rearrangement-cyclization are described.
