  Arylboronic Acids and Arylpinacolboronate Esters in Suzuki Coupling Reactions Involving Indoles. Partner Role Swapping and Heterocycle Protection

  摘要：

  Yields of Suzuki couplings involving indoles depended upon (i) whether arylboronic acids or arylpinacolboronate esters were used, (ii) whether the heterocycle was the aryl halide or the arylboron coupling partner, and (iii) whether the heterocycle was protected or not. Highest yields, which were unaffected by incorporating Boc or Tos protection at the heterocyclic nitrogen, were obtained when indole bromides were reacted with phenylboronic acids. When indolylboronic acids were reacted with phenyl bromides, yields were somewhat lower and depended on the nitrogen substituent, being highest in the absence of protection, lower in the presence of the Boc group, and lowest of all with the Tos group. Arylpinacolboronate esters were less reactive than arylboronic acids. They required considerably longer reaction times and furnished generally lower yields of biaryl. Furthermore, irrespective of whether the heterocycle was the aryl bromide or the arylpinacolboronate ester, these yields were highest when it was protected with the Tos group. Yields were lower with the Boc group, and unprotected heterocycles gave only traces of biaryl. Careful selection of arylboron reagent, of coupling partner roles, and of protecting groups are essential to ensuring optimum results in these Suzuki couplings. These results may also be relevant to couplings involving other substrates.

  emission tomography remains underexplored because convenient procedures for their radiosynthesis are lacking. Consequently, simple methods to prepare radiofluorinated (hetero)arenes are highly sought after. Herein, we report the beneficial effect of primary and secondary alcohols on Cu‐mediated 18F‐labeling. This observation contradicts the assumption that such alcohols are inappropriate solvents for

  由于缺乏方便的放射合成程序，许多18 F标记的（杂）芳烃在正电子发射断层显像中的应用潜力尚未得到开发。因此，强烈期望制备放射性氟化（杂）芳烃的简单方法。在此，我们报告了伯醇和仲醇对铜介导的18的有益作用。F标签。该观察结果与这样的醇与芳香族氟化不适合的溶剂的假设相矛盾。因此，我们开发了一种在一般反应条件下快速放射性标记硼和苯乙烯基底物的广泛范围的方案。值得注意的是，放射性氟化的吲哚，苯酚和苯胺是直接从相应的未保护的前体合成的。此外，该新方法还可以制备放射性氟化的色氨酸，[ 18 F] F-DPA，[ 18 F] DAA1106、6- [ 18 F] FDA和6- [ 18 F] FDOPA。
