An efficient and practical procedure was developed to prepare 7-azaindole, starting from an -haloaromatic amine and corresponding terminal alkynes under microwave irradiation and the scope was demonstrated with a number of examples. The valuable features of this procedure included the iron-catalyzed cyclization, short reaction times and convenient operation. Furthermore, iron catalysis is an interesting alternative to homogeneous catalysis for the synthesis of heterocycles.
开发了一种高效实用的方法,以卤代芳胺和相应的末端炔烃为原料,在微波辐射下制备7-氮杂吲哚,并通过多个实例展示了其适用范围。该方法的可贵之处包括铁催化环化、反应时间短和操作简便。此外,铁催化是合成杂环化合物时替代均相催化的一种有趣选择。
