A partial synthesis of isohibaene (VI) starting with nezukol (V) has been accomplished. It involves, as the key step, the intramolecular insertion reaction of a ketocarbene generated by cuprous oxide-catalyzed decomposition of diazoketone (XI) under irradiation. It has been found that isohibaene undergoes rearrangement into a mixture of phyllocladene (XIV) and isophyllocladene (XV) by iodine catalytically.
