The 2,6-dibromoindole 5 underwent regioselective Sonogashira coupling at the 2 position with simple acetylenic partners. While, the imidazole-acetylene 16 failed to couple to 5, the cyclic carbonate 19 succeeded to give 20, which was further elaborated into the indole-imidazole 23.
2,6-二溴吲哚 5 在 2 位与简单的炔属伙伴进行区域选择性 Sonogashira 偶联。虽然咪唑-乙炔 16 未能与 5 偶联,但环状碳酸酯 19 成功得到 20,进一步合成为吲哚-咪唑 23。
