本文介绍了溴三氯甲烷-DBU用于几种二氢杂环体系选择性氧化转化为相应的杂芳族化合物。在各种条件下考察了4-羟基-2-吡啶酮的氧化反应。苯硒化和过酸氧化反应的研究提供了新的螺环环氧乙烷。版权所有（C）1996 Elsevier Science Ltd
The use of bromotrichloromethane-DBU is described for the selective oxidative conversion of several dihydro-heterocyclic systems to the corresponding heteroaromatics. Oxidative dehydrogenations to afford 4-hydroxy-2-pyridinones are examined under a variety of conditions. Studies of phenylselenenylation and peracid oxidation provide the novel spirocyclic oxirane .
