An unprecedented rearrangement/anellation sequence allows the clean synthesis of azepino[3,4-b]indol-1-ones from readily available starting materials. Alkyne-substituted indole-3-carboxamides were prepared and converted to azepino[3,4-b]indol-1-ones by the SPhosAuNTf2 catalyst (SPhos=2-dicyclohexylphosphino-2',6'-dimethoxybiphenyl). The new connectivity, which involves an unprecedented 3,2-shift of an acylamino group for the product formation, was proven by a crystal structure analysis. Copyright
