Facile and efficient enantioselective hydroxyamination reaction: Synthesis of 3-hydroxyamino-2-oxindoles using nitrosoarenes
Sc takes action: The highly enantioselective hydroxyamination reaction of N-unprotected 2-oxindoles with nitrosoarenes has been realized using the Sc(OTf)3/L1 complex. The catalyst system exhibited remarkably broad substrate scope and high effi
