Heterocyclic derivatives of naphthoquinones were synthesized via their 2-bromo-2,3-dehydro-intermediates. This new route may lead to the formation of benzo[a]phenothiazin-5-ones, benzo[f]quinoxalin-6-ones as well as their 1,4 (or 7,10) dihydroxy-derivatives in high yields. The possible mechanisms involved in the formation of these compounds are discussed.
萘醌的杂环衍生物是通过它们的2-溴-2,3-脱氢中间体合成的。这种新途径可能导致高产率地形成苯并[ a ]吩噻嗪-5-酮,苯并[ f ]喹喔啉-6-酮及其1,4(或7,10)二羟基衍生物。讨论了涉及这些化合物形成的可能机理。
