    • Attempts at cleavage of the C3-pivaloyl enol ester were problematic, resulting in unproductive dihydro[3]benzazepine fragmentation. Moreover, attempts at reduction of the C3-C4 enol ester, either by conjugate addition protocols or hydrogenation protocols at hydrogen pressures up to 2500 psi, led only to its decomposition.
