C-Benzoyl-N-phenylnitrone (Ia) and C,N-diphenylnitrone (Ib) react with 2,3-dimethoxycarbonyl-7-oxabicycloheptadiene (II) to give endo- and exo-adducts at both the substituted double bonds.The endo-exo and site selectivity of 1,3-dipolar cycloaddition is discussed.Cycloadditions of the nitrones Ia and Ib to 5,6-dimethoxycarbonyl-7-oxabicycloheptene and 2,3-dimethoxycarbonyl-7-oxabicyclo-2-heptene are also described.
