6-diallyl-5-hydroxytropolone. The involvement of no cleavage-recombination process was established by cross-over deuterium labelling experiments. These derivatives were respectively converted to p-tropoquinones, one of which was further converted to a cyclohepta[b]pyranone derivative by an electrochemical reaction.
