A metal-guided method for divergent synthesis of ketone-fused indoles/pyrroles from N-(2-alkynylaryl) lactam is described. The reaction is proposed to proceed through a regioswitchable Friedel-Crafts cyclization of acylium. The obvious advantages are wide substrate scopes, high atom economy and step economy, which have a great potential in the synthesis of structure-related bioactive compounds.

Key words: Friedel-Crafts cyclization, ketone-fused indoles/pyrroles, divergent synthesis
