A new tandem cross enyne metathesis (CEYM)-intramolecular Diels-Alderreaction (IMDAR) has been carried out. It involves conjugated ketones, esters or amides bearing a remote olefin and aromatic alkynes as the starting materials. The overall process enables the preparation of a small family of linearbicyclic scaffolds in a very simple manner with moderate to good levels of diastereoselectivity. This
