Cyclobutanones derived from 1-naphthylketenes and 1,3-cycloalkadienes were prepared.These undergo acid rearrangements under a variety of conditions to give tetracyclic ketones.The tetracyclic ketones were converted to chrysene and substituted cyclopentenophenanthrenes.A mechanistic scheme is proposed for the rearrangement process.
