Application
It can be used to synthesize:
- 3,3-Disubstituted oxindoles via asymmetric Michael addition to oxindole.
- Bioactive isoindolines via asymmetric 1,3-dipolar cycloaddition to azomethine ylides generated in situ from aldehydes and diethyl aminomalonate.
- α,α-Difluoro-β-hydroxy ketone via ‘on water′ catalyst-free Mukaiyama-aldol reaction with difluoroenoxysilane.
- 2-Hydroxy-3-anilino-1,4-naphthoquinone, which shows potent in vivo antimalarial activity.
Additional appilcation include:
- As an arylation reagent for the α-arylation of aldehydes.
- As a starting material in the multi-step synthesis of benz[f]indole-4,9-diones.
