The intramolecular [2+3] cycloadditionreaction of the trimethylenemethanediyl generated from the intramolecular cyclopropanation reaction of alkylidene carbene produced linearly fusedtriquinanes regio- and stereoselectively. The current tandem cycloadditionreaction was applied to a 14-step total synthesis of hirsutene from methallyl alcohol.
