Abstract

A new Rh-catalyzed 1,6-enyne cycloisomerization process with a pi-allyl rhodium species as the key intermediate is investigated. A halogen shift happened in this novel process. The synthesis of stereodefined alpha-halomethylene gamma-butyrolactones has been achieved using the readily accessible Rh catalysts.
