New Entry to Polycyclic Fused Indoles via Gold(I)‐catalyzed Cascade Reaction

Abstract

The gold standard: A gold-catalyzed cascade reaction sequence for the preparation of polycyclic fused indole cores exploits the ready availability and chemical flexibility of propargylic alcohols. The desired tri- or tetracyclic compounds are obtained in good yields with water as the only stoichiometric by-product.
