Abstract Sulfamic acid was proved to be a cost-effective and recyclable catalyst for Friedel–Crafts type reaction of indole with α , β -unsaturated carbonylcompound and benzyl alcohol. Various indoles, α , β -unsaturated carbonylcompounds and a benzyl alcohol were successfully used in this type of reaction, and the corresponding products were obtained in good to excellent yields.
