A Catalytic Asymmetric Isatin-Involved Povarov Reaction: Diastereo- and Enantioselective Construction of Spiro[indolin-3,2′-quinoline] Scaffold
2013-01-04T00:00:00Z (GMT) by
The first catalytic asymmetric isatin-involved Povarov reaction has been established. This method provides an unprecedented approach to access the enantioenriched spiro[indolin-3,2′-quinoline] scaffold with concomitant creation of two quaternary stereogenic centers in high yields and excellent stereoselectivities (all >99:1 dr's, up to 97% ee).
