Abstract:A practical and efficient electrophilic substitution reaction of indoles with a variety of aldehydes was carried out using catalytic trichloro-1,3,5-triazine (10 mol %) in acetonitrile to furnish the corresponding bis(indolyl)methanes in excellent yields. Similarly, sugar derived aldehydes gave hitherto unknown bis(indolyl)glycoconjugates in very good yields.
Keywords:Bis(indolyl)methanes   Aldehydes   Sugar aldehydes   Electrophilic substitution   Trichloro-1,3,5-triazine
