for the intramolecularcyclization of tertiary alcohols with terminal alkynes to form diverse aza-spirocycles. The reaction was carried out with low catalyst loading under microwave irradiation to give both sulfonylated and acylated spirocyclic nitrogen derivatives. Gram scale spirocyclization was carried out to demonstrate the robustness of the reaction. An intramolecular Mizoroki-Heck reaction was performed
