An efficient and convenient bimetallic MnF2/CuI catalyst in combination with trans-1,2-diaminocyclohexane has been developed for the cross-coupling of nitrogen heterocycles with aryl halides in water at moderate temperature. A variety of nitrogen nucleophiles including pyrazole, 7-azaindole, indazole, indole, pyrrole and imidazole afforded the corresponding products in moderate to good yields (up to

iodides/bromides. The 1-arylated 7-azaindoles thus obtained were subjected to deprotometalation-iodolysis sequences using lithium 2,2,6,6-tetramethylpiperidide as the base and the corresponding zinc diamide as an in situ trap. The reactivity of the substrate was discussed in light of the calculated atomic charges and the pKa values. The behavior of the 1-arylated 7-azaindoles in direct iodination was then
首先比较了 7-氮杂吲哚和芳基/杂芳基碘化物/溴化物之间铜催化 CN 键形成的五种方案。使用2,2,6,6-四甲基哌啶锂作为碱和相应的二氨基锌作为原位捕集器,对由此获得的1-芳基化7-氮杂吲哚进行脱原金属化-碘解序列。根据计算的原子电荷和pKa值讨论了底物的反应性。然后研究了 1-芳基化 7-氮杂吲哚在直接碘化中的行为,并通过考虑 HOMO 轨道系数和原子电荷来解释结果。最后,产生的一些碘化物(通常是原始的)参与吲哚的N-芳基化。虽然收集了 15 种合成化合物的晶体学数据,但也评估了其他化合物的生物特性(抗菌、抗真菌和抗氧化活性)。

A practical and efficient strategy has been developed for the cross coupling of nitrogen heterocycles with halopyridines using ligand-free Cu2O as catalyst and Cs2CO3 as the base. The protocol is applicable to a series of highly functionalised heterocycles, such as 7-azaindole, indazole, indole, imidazole, pyrrole and pyrazole, affording the N-heteroaryl derivatives in high yields (up to 96%).
已经开发了一种实用且有效的策略,用于使用无配体的Cu 2 O作为催化剂和Cs 2 CO 3作为碱将氮杂环与卤代吡啶交叉偶联。该方案适用于一系列高度官能化的杂环,例如7-氮杂吲哚,吲唑,吲哚,咪唑,吡咯和吡唑,可提供高收率的N-杂芳基衍生物(最高96%)。
