Intramolecular 1,3-dipolar cycloaddition reaction offers a remarkably wide range of utility in the synthesis of complex cyclic natural products and macrocycles in less number of steps.1–3 Sydnones are easily accessible aromatic compounds and versatile synthetic intermediates with a masked azomethine imine unit. Their 1,3-dipolar cycloaddition with dipolarophiles such as alkenes and alkynes is a convenient
