title: Regioselective synthesis of the tricyclic core of lateriflorone.
abstract: An efficient synthetic approach to the tricyclic core 8 of lateriflorone is described. Essential to the synthesis was the implementation of a biomimetic tandem Claisen/Diels-Alder reaction that produced the desired tricyclic scaffold as a single isomer. A rationalization of the excellent regio and stereoselectivity of this transformation is also proposed. [reaction: see text]
