A rapid construction of the ABC ring of wallichanol is described. The synthesis features an efficient Diels-Alder reaction for the bicyclo[2.2.2]octane synthesis and a gold-catalyzed alkyne carbometalation for the cyclobutane synthesis. The overall yield of this 7-stepped synthesis is 42%. This strategy can pave the road towards the total synthesis of wallichanol.
Key words: wallichanol; Diels-Alder reaction; carbometalation; total synthesis
