Abstract

The one-electron oxidation of cyclobutanols to give y-keto radicals is well-known. We wanted to develop procedures that would permit the acyclic y-keto radical to be trapped by cyclization to a proximate double bond to give a new cyclic structure. The double bond could be conjugated to the ketone produced in the fragmentation as shown in eq 1 or attached to the cyclobutane fragment by a tether as shown in eq 2. We have developed a class of ...
