The direct functionalization of quinones has always fascinated research communities due to
their biological and redox activities and subsequent application. Quinone motifs play a vital …

Developing methods for the direct functionalization of quinones for assembly of highly
functionalized quinones or bioactive natural products is an essential topic in the field of …

The oxidative addition of anilines (2) with 1, 4-naphthoquinone (3) to give N-aryl-2-amino-1,
4-naphthoquinones (1) was found to be catalyzed by copper (II) acetate. In the absence of …

Progress in Heterocyclic Chemistry (PHC) is an annual review series commissioned by the
International Society of Heterocyclic Chemistry (ISHC). Volumes in the series contain both …

Eleven 2, 3-(substituted)-1, 4-naphthoquinone derivatives were synthesized in yields
ranging from 52-89%. These derivatives were evaluated for their cytotoxic effects on human …

The palladium-catalyzed efficient cross-couplings of mono-, di-and tetra-bromo-1, 4-
quinones with triarylbismuth reagents were developed, involving threefold arylation. This …

The reaction of P (O) H compounds with p‐quinones could proceed through either 1, 4‐or
1, 6‐addition pathways by employing different additives to selectively give the …

A series of 2, 5-substituted-1, 4-benzoquinone (1–6) were prepared and structurally
characterized by elemental analysis, IR spectra, 1H and 13C NMR spectra, and single …

We synthesized ten enamine naphthoquinones with yields ranging from 43 to 76%. These
compounds were screened for their in vitro antiproliferative activities by MTT assay against …

We have studied the enzymatic derivatization of amino acids by use of the polyphenol
oxidase laccase. Derivatization of L-tryptophan was achieved by enzymatic crosslinking with …
