| Abstract: | The 1,3-dipolar cycloaddition of unstabilized azomethine ylide, which is generated in situ from isatin and thiaproline, to arylidene derivatives of rhodanine affords bis-spirofused thiapyrrolizidinooxindoles. The 1,3-dipolar addition reactions under consideration are fully regio- and diastereoselective. |
