Suzuki交叉偶联和N-芳基化反应的组合合成4-芳基,2,4-二芳基和2,4,7-三芳基吡咯并[2,3- d ]嘧啶
摘要:
一种简单而又容易的合成新型4-芳基-2-氯-,2,4-二芳基-和2,4,7-三芳基吡咯并[2,3- d ]嘧啶的杂环骨架,其中的芳基和杂芳基是通过描述了2,4-二氯吡咯并[2,3- d ]嘧啶与芳基硼酸和卤代芳烃的Suzuki交叉偶联和N-芳基化反应的组合。发现大多数合成化合物在近紫外-蓝色光谱范围内发射,荧光量子产率高达67%。讨论了连接到吡咯并嘧啶衍生物的吡咯环上的芳基对光学性能的影响。

A simple and facile synthesis of novel fluorescent pyrrolo[2,3-d]pyrimidines with various aryl and heteroaryl assemblies in positions 2, 4, and 7 of the heterocycle by combination of the Suzuki cross-coupling and copper(I) iodide N-arylation reactions of chloropyrrolo[2,3-d]pyrimidines with arylboronic acids and haloarenes is described.
