A one-pottandem process involving an Overman rearrangement, ring closing enyne metathesis and a hydrogen bonding directed Diels-Alder reaction has been developed for the efficient diastereoselective synthesis of functionalised amino substituted tetralin and indene ringsystems.

A rapid and diastereoselectivesynthesis of highly substituted aminobicyclo[4.3.0]nonanes and bicyclo[4.4.0]decanes from alkyne derived allylicalcohols has been developed using a one-pot multi-bond forming tandem catalytic process. Overmanrearrangement of the allylic trichloroacetimidates was followed by a ring closing enyne metathesis/cross metathesis sequence of reactions, in which both steps were
