Medium-Ring Ketone Synthesis. Total Syntheses of (+/-)-Isocaryophyllene and (+/-)-Caryophyllene

Total syntheses of (+/-)-isocaryophyllene and (+/-)-caryophyllene are reported.The key step involves a novel construction of the nine-membered ring in these natural products by a base-induced intramolecular acyl transfer reaction of 13-membered lactam sul
