Abstract

A double enyne metathesis reaction has been developed for the efficient synthesis of tricyclic products with a benzene core in good yields. By this protocol, bisannulated benzenes with different ring sizes may be simultaneously constructed from the corresponding precursors in just 'one shot'.
