摘要
A palladium-catalyzed ring-opening oxo-formal [3 + 2]-cycloaddition reaction of novel donor–acceptor spirovinylcyclopropyl oxindole with 3-oxindole is described. The developed protocol provides facile access to oxo-bispirooxindole derivatives in good yields (up to 82% yield) with excellent diastereoselectivities (up to 20:1 dr).
