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.

Here we report a series of 2-aryl-3-amino-1,4-naphthoquinones that generated reactive oxygen species (ROS) such as superoxide and hydrogen peroxide upon incubation in pH 7.4 under ambient aerobic conditions. ROS generation from these compounds was sensitive to structural modifications at the

In their inhibition-inducing interactions with enzymes, quinones primarily utilize two mechanisms, arylation and oxidation of enzyme thiol groups. In this work, we investigated the interactions of 1,4-naphthoquinone with urease in an effort to estimate the contribution of the two mechanisms

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
