Peduncularine, the principal alkaloid of the Tasmanian shrub Aristotelia peduncularis, was synthesized via the radical cyclization of 7-oxabicyclo[2.2.1]hept-2-en-5-yl ketone oxime 9 forming the 6-...

An efficient Lewis acid induced nitrogen-driven rearrangement iminium-trapping cascade from an epoxytropinone 3 gives a 7-allylated 6-azabicyclo[3.2.1]octan-3-one 2, which is converted into the alkaloid (±)-peduncularine (1).
