Abstract

The intramolecular photochemical cycloaddition reaction of cyclic enones with a tethered alkene was first reported over 80 years ago by Ciamician and Silber who found that carvone was converted to carvone camphor on exposure to “Italian sunlight”(Scheme 1).* In recent years this intramolecular reaction has frequently been utilized for the synthesis of complex ring systems and natural product^.^ A major attraction of the reaction is that the tether ...
