Application

1,4-Naphthoquinone is the key structural moiety of many anticancer and antifungal agents.
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.
