Regiospecific nucleophilic substitutionreactions involving attack of the nitrogen atom of oximes on epoxides are used to generatenitrones which are then trapped in 1,3-dipolar cycloadditionreactions. These tandem processes are shown to be flexible and to have wide synthetic scope for the construction of complex molecular frameworks.
