Key words
all-carbon quaternary stereocenters - intramolecular Heck reaction - oxindoles - palladium catalysis
Significance
In 2003, Overman and co-workers disclosed a palladium(0)-catalyzed asymmetric intramolecular Heck cyclization to form oxindoles with an all-carbon quaternary stereocenter in high enantioselectivities.
#
Comment
The synthesis of 3-alkyl-3-aryloxindoles by catalytic enantioselective Heck cyclization was implemented in the total synthesis of several natural products.
