A concise approach to synthesize the 5-7-6 tricyclic carbon skeleton of the daphnane/tigliane diterpene natural products has been accomplished via a sequential gold-catalyzed furan formation and furan-allene [4+3] cycloaddition. This work provides new avenues for rapid and diverted synthesis of the medicinally important daphnane/tigliane diterpenes and their unnatural analogues.
