A general DBU/NBS-mediated one-pot three-component cycloaddition reaction of easily accessible malonic acid derivatives, nitrosoarenes, and alkenes provides direct access to highly functionalized isoxazolidine derivatives with very good yields, broad functional group tolerance, and excellent regio- and diastereo-selectivities under mild conditions.
