Tri‐ and tetracyclic heterocycles were formed through the tandem cyclization of allenenes 1 upon treatment with an aryl iodide, potassium carbonate, and catalytic [Pd(PPh 3 ) 4 ] (see scheme). The reactivity of the palladium( II ) intermediates could be controlled by substitution (R′) at the olefin terminus (Mts=2,4,6‐trimethylphenylsulfonyl).
