A highly periselective cycloaddition of cycloheptatriene and cyclohexa-2,4-dienones(2a-c) to endo tricyclic systems (6a-c) and their photo conversion to cage compunds (7a-c ) has been reported. It has been shown that the adduct 6c arise via Cope rearrangement of the initially formed pi4s(dienone) + pi2s(CHT) adduct 5c.
