Intramolecular Pauson–Khandreaction of various alkynyl exo-alkylidene-cyclohexanes and -pentane gives angular type 6–5–5 and 5–5–5 tricyclic compounds in good to high yield. The present reaction also offers convenient construction of two contiguous quaternary centers, which could not be synthesized from alkynyl endo-cycloolefins. Scope and limitation of the present reaction of various exo- and endo-cyclic
