- 論文の詳細を見る
Unlike the benzenoid equivalent, <I>p</I>-methoxyphenol, the cerium(IV) ammonium nitrate (CAN)-oxidation of 5-hydroxy-2-methoxytropone gave C–C coupling products. On the other hand, either by thallium(III) nitrate (TTN) or CAN at 50 °C, 5-hydroxytropolone, a free tropolone, gave 3-methoxy-<I>p</I>-tropoquinone together with <I>p</I>-tropoquinone and 8-oxabicyclo[3.2.1]octenone derivatives, but no dimeric product.
