A titanocene-mediated intramolecular radical addition of different epoxy vinyl- and allylsulfones has been achieved. Five- and six-membered ring products were obtained in good to excellent yields in the presence of both 2.2 and 0.2 equiv of Cp2TiCl. A novel double-activation strategy allowed us to achieve small-size rings such as cyclobutanes and cyclopropanes. (Chemical Equation Presented).

Allyl 2-pyridyl sulfide 6 or allyl phenyl sulfone 7 on treatment with n-butyllithium in tetrahydrofuran followed by tri-n-butylstannylmethyl iodide (4) afforded directly the 1,3-diene 8 in good yield.
