radical cyclization constitute the central steps of two alternative approaches developed to assemble the tricyclic ABC substructure of the indolealkaloidapparicine. From this key intermediate, an intramolecular vinyl halide Heck reaction accomplished the closure of the strained 1-azabicyclo[4.2.2]decane framework of the alkaloid with concomitant incorporation of the exocyclic alkylidene substituents
