, p. 942 - 944 (2006)
A convenient one-step synthesis of 2-[(nitroaryl)amino]-3-chloro-1,4- naphthoquinones is reported. The direct amination of 2,3-dichloro-1,4- naphthoquinone with nitro-substituted aryl amines is catalyzed by PdCl 2(dppf)/dppf in the presence of

2-chloro-3-(R-anilino)-1,4-naphthoquinones react with sodium azide upon refluxing in DMF. The thermochemistry of 2-azido-3-(R-anilino)-1,4-naphthoquinone is strongly modified by the substituent on aniline. Having an strong electron-donor like O-R results
Synthesis and studies of the antifungal activity of 2-anilino-/2,3-dianilino-/2-phenoxy- and 2,3-diphenoxy-1,4-naphthoquinones

Several synthetic and natural naphthoquinone derivatives have been associated with antifungal activity. Candida albicans is a fungus that is known to exist in the normal human flora, but under certain conditions it can cause mild to fatal infections. Its pathogenicity has been associated with fungus conversion from cellular yeast to filamentous form Y–M. Inhibition of this process by several anilino-, dianilino-, phenoxy-, and diphenoxy-1,4-naphthoquinones was investigated in order to find some correlation between structure, redox properties and biological activity.
Synthesis of novel 2-(fluoroanilino)-3-(2,4-dinitroanilino) derivatives of 1,4-naphthoquinone

Several novel 2-(fluoroanilino)-3-(2,4-dinitroanilino) derivatives of 1,4-naphthoquinone have been synthesized in good to excellent yields. First, 2-chloro-3-(2,4-dinitroanilino)-1,4-naphthoquinone was prepared in two steps beginning with the reaction of
Direct nitration of 3-arylamino-2-chloro-1,4-naphthoquinones
Win, Thida,Yerushalmi, Sarit,Bittner, Shmuel
, p. 1631 - 1634 (2007/10/03)
A convenient two-step synthesis of mononitro and dinitro derivatives of the title compounds is reported. The Michael type addition of aromatic amines to 2,3-dichloro-1,4-naphthoquinone, is followed by mixed acids nitration to yield nitro aromatic quinones
