Substituted spiro[isoxazolidine-3,2'-tricyclo[3.3.1.1(3,7)]decane] derivatives

The preparation and potential anti-inflammatory activity of a series of novel substituted spiro[isoxazolidine-3,2'-tricyclo[3.3.1.1(3,7)]decanes] (7, 11-30) are reported. The synthesis of the title compounds was accomplished via a 1,3-dipolar cycloaddition reaction of nitrones with appropriate olefins.
