Benzofuran derivatives and bisindolylmethane derivatives are widely present in natural products, and have significant biological activity. Acetals were demonstrated to be efficient alkylating agents in the presence of TMSOTf and 2,4,6-collidine. Bisbenzofuranmethane and bisindolylmethane derivatives were easily obtained via direct alkylation of benzofurnan or indole with a series of acetals including amino, cyclic, acetone, aryl and alkyl acetals. The reaction mechanism was proposed.

Key words: benzofuran, indole, acetal, alkylation
