general and convenient synthetic route to various 2-aryl-N-tosylazetidines has been described. Their ZnX2 (X = I, OTf) mediated nucleophilic ring opening with halides and [4+2] cycloaddition reactions with various nitriles have been achieved to afford γ-iodoamines and substituted tetrahydropyrimidines, respectively, in good to excellent yields. A mechanism for the cycloaddition reaction is proposed
