A new strategy for the construction of the isotwistane skeleton is reported from easily available cyclohexadienes, which involves a one-pot cationic skeletal rearrangement and ene cyclisation of a bicyclo[2.2.2]octenone derivative and a cationic rearrangement of a tricyclo[5.3.0.04,8]decane to a [4.3.1.03,7]decane skeleton as the key steps in the synthesis of 2-pupukeanone.
