Résumé
A new tandem reaction leads to bicyclic cyclohexene derivs., e. g. I, with complete control of the relative configuration of the four chiral centers formed. The high diastereoselectivity is the consequence of an endo-selective Diels-Alder reaction followed by an Ireland-Claisen rearrangement that proceeds via a boat-like transition state.
