A pinacol-type rearrangement of intramolecular photocycloadducts has been accomplished by exploiting a novel ester protecting group that can be easilyremoved from a hindered alcohol. The ester is removed by an intramolecular lactonization, overcoming the steric factors normally associated with pivalate esters.
