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.

Organic cathode materials are promising cathode materials for multivalent batteries. Among organic cathodes, anthraquinone (AQ) has already been applied to various metal‒organic systems. In this work, we compare electrochemical performance and redox potential of AQ with 1,4-naphthoquinone (NQ) and 1,4-benzoquinone

Improving the solubility of polysubstituted 1,4-naphthoquinone derivatives was achieved by introducing nitrogen in two different positions of the naphthoquinone core, at C-5 and at C-8 of menadione through a two-step, straightforward synthesis based on the regioselective hetero-Diels-Alder reaction. The antimalarial

Despite intensive research, there are very few reagents with which to modulate and dissect the mRNA splicing pathway. Here, we describe a novel approach to identify such tools, based on detection of the exon junction complex (EJC), a unique molecular
