摘要

Abstract In the presence of triethylsilane and trifluoroacetic acid, the reaction between indoles and aldehydes in dichloromethane at 0 C, results in good yields of C-3 reductively alkylated products. The transformation is most effective for the preparation of 3-(arylmethyl) indoles 6 from aromatic aldehydes.
