The easily accessible 2-aryl-1,1-dibromo-1-alkenes can be converted to amides under unusually mild conditions in good to excellent yields. Both electron-donating and electron-withdrawing substitutions on the aromatic rings are tolerated, and the reaction works well with hindered alkylamines. This simple homologation could find broad applications. [reaction: see text]

Examples of the quinolizidine and benzoquinolizidine ring systems (1,1-bisethoxycarbonyl-4-oxo-quinolizidine, 1,3,4,6,7,11b-hexahydro-2H-benzoquinolizidine, and 1,2-t-butyl-3,4,6,7,11b-hexahydro-2H-benzo-quinolizidine) have been synthesized by routes which involve initial anodic methoxylation of piperidine precursors with subsequent intramolecular Lewis acid-catalysed cyclisation reactions.Reaction conditions for such cyclisations have been explored; success depends on a correct choice of catalyst (usually aluminium chloride) and, critically, on steric factors.The stereochemistry of the cyclic products has been established and the stereochemical course of the reactions is commented upon.
