摘要: AbstractAn efficient procedure for the synthesis of bisindolylmethanes from condensation indole and aromatic aldehydes or ketones is described. The electrophilic substitution reactions with are achieved in presence tetrabutylammonium hydrogen sulfate as a mild solid acid catalyst. This methodology offers several advantages such good yields, simple procedure, environmentally benign conditions.
