Abstract

Benzo[b]carbazoles can be synthesised readily and in good yields from the combination of 2,3-unsubstituted indoles and o-phthaldialdehyde in the presence of acid catalysts. Use of phosphoryl chloride in chloroform gives rapid reactions and yields 11-(3-indolyl)benzo[b]carbazoles, whereas the use of p-toluenesulfonic acid in methanol gives slow reactions and yields the isomeric 6-(3-indolyl)benzo[b]carbazoles.
