Abstract

A novel one-pot synthesis of N-substituted heterocycles via successive cyclization/annelation starting from primary sulfonamides is described. This process directly leads to N-sulfonyl pyrroles, indoles and carbazoles. The selection of an appropriate reactant/triflic acid ratio successfully controls the formation of the desired product.
