title: N-heterocyclic carbene-catalyzed synthesis of spirocyclopentene-oxindoles from bromoenals.
abstract: The N-heterocyclic carbene-catalyzed tandem reaction of bromoenals and oxindoles was developed to give the corresponding chiral spirocyclopentene-oxindoles in good yields with good to high diastereo- and enantioselectivities.
