substituted phenols in the presence of (diacetoxyiodo)benzene promotes the formation of a phenoxenium ion, a very electrophilic species able to react with various nucleophiles leading rapidly to a plethora of different cores present in natural products via several novel oxidative processes. This strategy fits within the concept of ‘aromatic ring umpolung’; in this paper a personal account by our laboratory
在(二乙酰氧基碘)苯存在下处理各种取代的苯酚会促进苯氧en离子的形成,苯氧en离子是一种非常亲电的物种,能够与各种亲核试剂反应,通过几种新颖的氧化过程迅速导致天然产物中存在过多的不同核心。该策略符合“芳香环保护”的概念;本文描述了我们实验室对此主题的个人描述。
