Two 1,3,8,10-undecatetraenes were synthesized to test the viability of the intramolecular radical cation induced Diels-Alder reaction in the diene - diene format. Cyclization was successful only for the substituted tetraene with the lower oxidation p

The electrocyclic opening of dibromocyclopropane derivatives containing a tethered diene unit provides a good route to trienic cyclopentane derivatives. In one instance a bicyclic product arising from a fromal 4 + 2 cycloaddition process was observed
