dc.description.abstract© the Partner Organisations 2019. A [3 + 2] annulation between the Morita-Baylis-Hillman (MBH) carbonates and pyrazoloneyldiene oxindoles catalyzed by (S)-SITCP has been developed. Structurally novel bispiro[pyrazolone-3,3′-oxindoles] containing two contiguous quaternary stereogenic centers were created in excellent yields, in a diastereospecific and highly enantioselective manner.
