3,5‐Dihydrobenz[ f ]indolizin‐3‐one was prepared by a novel dehydration reaction involving the heating of 1,2,3,5,10,10a‐hexahydro[ f ]indolizine‐3,10‐dione with polyphosphoric acid. The structure of this new compound was established by X‐ray crystallography, by nmr spectroscopy and by reduction to the known products 1,2,3,5‐tetrahydrobenz[ f ]indolizin‐3‐one and 1,2,3,5,10,10a‐hexahydrobenz[ f ]indolizin‐3‐one.
