Double Gold‐Catalysed Annulation of Indoles by Enynones

The gold-catalysed double functionalisation of indoles is presented. Enynones are used to annulate indoles via a double sodium tetrachloroaurate-catalysed process involving a mixture of C[BOND]H activation and alkyne activation modes of promotion. Good yields for the formation of medicinally relevant [6,5,7]-tricyclic indoles are realised.
