以2-(2-溴苯基)乙腈为原料,一锅法合成了1-苯基- 1h -吲哚-2-胺和5-氨基-吲哚[1,2-a]喹唑啉衍生物。整个过程包括Buchwald-Hartwig型偶联和碱基促进的分子内亲核反应。讨论了反应范围、优点和局限性。
An efficient and practical one-pot domino synthesis of 1-phenyl-1H-indol-2-amine and 5-amino-indolo[1,2-a]quinazoline derivatives from readily available 2-(2-bromophenyl)acetonitriles was developed. The overall protocol involves a Buchwald-Hartwig type coupling and a base-promoted intramolecular nucleophilic reaction. The reaction scope, advantages and limitations are discussed.
