资源简介：
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).
