A series of O- and N-α,ω-enyne derivatives of 2-iodoarylethers and 2-iodoarylamides undergo palladium catalysed cascade hydrostannylation of the ω-alkyne moiety at 0-25°C followed by bis-cyclisation at 100-110°C terminating in intramolecular sp3-sp2 Stille coupling. These cascades provide a wide range of 5/6 and 5/12-17 membered bicyclic spiro- and bridged-ring heterocycles. (C) 2000 Elsevier Science Ltd.
