Simple use of KOH allows the direct F to OH exchange of aromatic and heteroaromatic substrates under mechanochemical conditions. The reaction is performed in the absence of solvent with potassiumhydroxide as OH source. As a result, this approach is both more atom economical and environmentally friendly than previously described methods for this transformation.
简单地使用 KOH 可以在机械化学条件下实现芳族和杂芳族底物的直接 F 到 OH 交换。该反应在没有溶剂的情况下以氢氧化钾作为OH源进行。因此,这种方法比之前描述的这种转化方法更原子经济和环境友好。

Canthin-6-one (1) and nine analogues Including the naturally occurring 9-methoxycanthin-6-one (2) and amaroridine (3) are prepared rapidly and in high yields via a convergent "non-classical" strategy that focuses on construction of the central ring B. The strategy relies on concomitant Pd-catalyzed Suzuki-Miyaura C-C coupling followed by a Cu-catalyzed C-N coupling that can be achieved either stepwise or in a new one-pot protocol starting from the appropriate 8-bromo-1,5-naphthyridine.
