A novel K3PO4-catalyzed synthesis of polysubstitutedpyrroles by a Michael addition/alkyne carbocyclization of activatedalkynes and N-propargylamines has been developed. This transition-metal-free cascade process represents an environmental friendly and efficient way to construct polysubstitutedpyrroles in good yields. Catalyzed by CsF, a Michael addition/aza-Claisen rearrangement/cyclization sequential

regioselectivity and moderate to good yields. A novel synthesis of 2-iminoimidazoles and 2-aminoimidazoles, via nucleophilic addition and a subsequent sodium hydroxide mediated intramolecular alkyne hydroamination from propargylamines and carbodiimides, is developed. This transition-metal-free cascade process represents an atom-economic and step-economic procedure for the construction of imidazole derivatives with
