A new method was developed to prepare N¹ and N²-indol-3-yl 1,2,3-trizole products through gold catalyzed cascade reaction of o-alkynyl arylazides with 1,2,3-triazoles, in which, the in-situ generated α-imino gold carbene intermediate was intercepted by various types of triazole compounds. N¹-selective nucleophilic attack was favored to give moderate to high N¹/N² selectivity. In addition, indol-3-yl pyrazole compounds were also prepared by using the similar method.

金催化2-炔基芳基叠氮化物与1,2,3-三唑的级联反应，以提供N ^1-和N ² -Indol-3-yl 1,2,3-三唑衍生物

的新方法的开发是为了准备Ñ ¹和Ñ ² -通过金催化级联反应吲哚-3-基-1,2,3-三唑产品ø -炔基芳基叠氮化用的1,2,3-三唑，其中，所述在原位生成的α-亚氨基金卡宾中间体被各种类型的三唑化合物拦截。N ^1-选择性亲核攻击有利于产生中等至高的N ¹ / N ²选择性。另外，吲哚-3-基吡唑化合物也通过使用类似方法制备。
