Creation of bispiro[pyrazolone-3,3 '-oxindoles] via a phosphine-catalyzed enantioselective [3+2] annulation of the Morita-Baylis-Hillman carbonates with pyrazoloneyldiene oxindoles. ORGANIC CHEMISTRY FRONTIERS 6 (13) : 2210-2214. ScholarBank@NUS Repository. https://doi.org/10.1039/c9qo00471h | 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. | Source Title: | ORGANIC CHEMISTRY FRONTIERS | URI: | https://scholarbank.nus.edu.sg/handle/10635/169692 | ISSN: | 20524129 | DOI: | 10.1039/c9qo00471h |
