A fluoride-induced termination of Prinscyclization has been observed using a tethered alkyne and stoichiometric amounts of AgSbF6 and found to generate a novel series of 6-fluoro-1-aryl-hexahydro-1H-isochromene derivatives in good yields with excellent selectivity. This is the first report of the synthesis of fluoro-substituted oxabicycles. In this tandem process, three reactions occur in one-pot
