Upon thermal activation the newly synthesized heptahendecafulvadiene E (=3) is isomerised into the pentacyclic hydrocarbons 9/11 (xylene, t1/2 (150 deg C) ca. 5 min), the formation of which is explained by initial conrotatory 20-electron electrocyclisation followed by a cascade of 10?/6?-pericyclic processes.
