以2-芳基吲哚和炔丙基醚为原料，在铟催化下，合成了一系列芳基和杂芳基环化的[a]咔唑。使用九氟丁磺酸铟作为催化剂可获得最佳结果。该策略也适用于联噻吩和联呋喃的成环反应。
The new method for the synthesis of a wide range of aryl-and heteroaryl-annulated [a] carbazoles consists of an indium-catalyzed reaction of 2-arylindoles with propargyl ethers. Best results are achieved using indium nonaflate as catalyst. The strategy is also applicable to the annulation of bithiophenes and bifuran.
