title: Lewis acid catalyzed unprecedented [3 + 2] cycloaddition yields 3,3'-pyrrolidinyldispirooxindoles containing four contiguous chiral stereocenters with two contiguous quaternary spirostereocenters.
abstract: A Lewis acid catalyzed domino reaction cascades through azide-alkene cycloaddition, rearrangement, aziridine ring opening, and azomethine cycloaddition with a parent dipolarophile, resulting in 3,3'-pyrrolidinyldispirooxindoles containing four contiguous chiral stereocenters with two contiguous quaternary spirostereocenters.
