Abstract
We report the first organocatalytic activation of monofluorinated silyl enol ethers 1, by nucleophilic tertiary amine catalysis, to develop asymmetric reactions for the construction of fully substituted chiral carbons featuring a C–F bond. Accordingly, a highly stereoselective Mukaiyama-aldol reaction of isatins to furnish hydroxyoxindoles bearing two adjacent tetrasubstituted carbon stereocenters is developed.
