The 1,3-dipolar cycloaddition of nitrones to vinyl ethers is accelerated by Ti(IV) species. The efficiency of the catalyst parallels its complexation capacity. The use of Ti(iprO)2Cl 2 favours the formation of trans cycloadducts, presumably through an endo bidentate complex, in which the metal atom
