Potassium tert-Butanolate Promoted Reaction ofBenzaldehydes and Indoles： a New Strategy for Synthesis of Bis（indolyl）arylmethanes

摘要

t-BuOK-promoted synthesis of bis（indolyl）arylmethunes from aromatic aldehydes and indoles wasachieved. Substrates bearing different functional groups, especially groups which are sensitive to acidic media, arewell tolerated under the optimal condition, making this reaction particularly attractive for expanding the scope of thepresent protocols that provides bis（1H-indol-3-yl）arylmethanes.
