1,3-dipolar cycloaddition reactions of C-(2-nitro)-styryl-N-phenyl nitrone leading to the regiospecific and stereospecific synthesis of new isoxazolidine derivatives

New substituted isoxazolidine derivatives have been synthesized through regiospecific and stereospecific 1,3-dipolar cycloadditions of C-(2-nitro)-styryl-N-phenyl nitrone with reactive dipolarophiles in excellent yields and effects of substituents have been noted.
