A new strategy for the synthesis of pyrrole through intramolecular cyclization of γ-alkynyl oximes promoted by SmI2 is reported for the first time. In contrast to the prior methods, the selection of oxime instead of oximeether or ester as substrate makes the synthetic method without accompaniment of organic waste (ArCO2H, AcOH, or ROH) because the hydroxyl group in oxime acts as the leaving group
