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).

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-...

Intramolecular photocycloaddition of 41 or its equivalent leads to the formation of photoadduct 25. While retro-Mannich fragmentation of the "b" bond in 25 leads to the formation of 44 (via 43), with the incorrect relative stereochemistry for the syn

[reaction: see text] The formal synthesis of the alkaloid (+/-)-peduncularine (1) was accomplished through the use of a [3 + 2] allylic silane annulation. The annulation of cyclohexadienyl silane 6 with chlorosulfonyl isocyanate followed by an in sit

[reaction: see text] A synthesis of the 6-aza[3.2.1]bicyclooctene (-)-2 has been completed by a short sequence of reactions that required only six operations from (S)-malic acid and featured a novel ring-closing metathesis to form the bridged bicycli
