An effective microwave‐induced, solid acid‐catalyzed, environmentally benign synthesis of substituted pyrroles, indoles and carbazoles under solvent‐free conditions is described. The new synthetic methodology is based on the use of a considerably strong solid acid, K‐10 montmorillonite. Both the cyclialkylation of amines and annelation of pyrroles and indoles have been completed within minutes and provided excellent (75–98 %) yields with practically 100 % selectivity.
