摘要：

A highly efficient tandem double Friedel-Crafts reaction between indoles and 2-formylbiphenyl derivatives by chiral N-triflyl phosphoramide was realized. Under mild conditions, various 9-(3-indolyl)fluorene derivatives have been obtained in good yield and up to 94% ee. Comparing to their corresponding chiral phosphoric acids, chiral N-triflyl phosphoramides catalyzed reactions led to products with opposite absolute configuration.
