title: Versatile strategy to access tricycles related to quassinoids and triterpenes.
abstract: The reactivity of two new bicyclic cyclohexenones (13 and 27) with several Nazarov reagents is presented. A flexible synthetic strategy is developed and provides access to highly substituted tricycles related to quassinoids and triterpenes.
