Soley, Roger; Albericio Palomera, Fernando; Álvarez Domingo, Mercedes (2014-07-04)

A new and easy synthesis of 2-arylethynyl-indole and 2-arylethynyl-pyrrole is described. N-deprotection and subsequent base-catalyzed elimination of N-tosylheteroaryl benzyl ketones are the key steps of the process.
