Bis- and tris(1H-indol-3-yl)methanes are synthesized in high yields by an electrophilic substitution reaction of indoles with carbonyl compounds under mild reaction conditions using two efficient heterogeneous catalysts, silica supported sodium hydrogen s

An I2-mediated Friedel-Crafts alkylation/oxidative coupling reaction of indoles and salicylaldehydes was developed. With the developed protocol, a series of indolylchromeno[2,3-b]indoles were obtained in good yields (up to 88%) under mild reaction conditions. Two possible reaction mechanisms were tentatively brought forward to account for the formation of the products in light of some control experiments.

, p. 327 - 330 (2007/10/03)
Silica chloride has been applied as a catalyst for the first time for rapid synthesis of bis-indolylmethanes in excellent yields by electrophilic substitution reaction of indoles with carbonyl compounds under microwave irradiation. The process is environm
Electrophilic Substitution of Indoles: Part IX - Reaction of Indoles with Iminium Systems
Banerji, J.,Saha, M.,Chakrabarti, R.,Das, A. K.,Pandit, U. K.,et al.
, p. 1204 - 1208 (2007/10/02)
The electrophilic substitution of indoles with iminium systems has led to the synthesis of new and interesting heterocyclic compounds, the structures of which have been settled from detailed 1H and 13C NMR studies.
