Described herein is an efficient copper-catalyzed tandem alkyne indolylcupration-initiated 1,2-indole migration/6π-electrocyclic reaction of allene-ynamides with indoles by the in situ-generated metal carbenes. This method allows the efficient synthesis of valuable indole-fused spirobenzo[f]indole-cyclohexanes with high regio- and stereoselectivity. In addition, this reaction affords rapid access to
本文描述的是通过原位生成的金属卡宾进行的铜催化串联炔吲哚基引发的丙二烯-炔酰胺与吲哚的1,2-吲哚迁移/6π-电环反应。该方法可以有效合成具有高区域和立体选择性的有价值的吲哚稠合螺苯并[ f ]吲哚环己烷。此外,该反应可以在不存在吲哚的情况下,通过含铜全碳1,4-偶极子进行可能的5-exo-dig环化/弗里德尔-克来福特烷基化,快速获得官能化的螺苯并[ f ]吲哚-环己烷。
