Abstract
The use of bromotrichloromethane-DBU is described for the selective ox idative conversion of several dihydro-heterocyclic systems to the corr esponding heteroaromatics. Oxidative dehydrogenations to afford 4-hydr oxy-2-pyridinones are examined under a variety of conditions. Studies of phenylselenenylation and peracid oxidation provide the novel spiroc yclic oxirane <(10)under bar>. Copyright (C) 1996 Elsevier Science Ltd
