The pseudo-four component click synthesis of dibenzylated 1,2,3-triazoles derived from aniline is reported. The cycloaddition of sodium azide to N-(prop-2-ynyl)-benzenamine (I) in the presence of equimolar amounts of p-substituted benzyl derivatives, yields a mixture of mono- and dibenzylated 1,2,3-triazoles. When two equivalents of the benzyl derivative are added to the multicomponent reaction...

While searching for novel nonsteroidal inhibitors of human and rat prostatic 5alpha-reductases, we found a new series of indoline and aniline derivatives that showed potent inhibitory activities for both enzymes. Among them, 3-chloro-4-¿[1-(4-phenoxybenzyl)indolin-5-yl]oxylbenzoic acid (2e, YM-36117) showed a more potent inhibitory activity for the human enzyme than ONO-3805 with an IC50 value ...

Three different aniline derivatives, namely m- and p-aminobenzoic acids and m-amino benzenesulfonic acid, were sequestered in between layers of a borate-based coordination polymer, based on lead(II) tetrakis(imidazolyl)borate. The aniline derivatives pre-organized in the interlayer spacing of the coordination polymer, and the reactivity of these pre-organized anionic monomers in the crystalline...

The reaction of aniline (AH2) with an oxidizing agent in acidic solution gives rise to the formation of a mixture of products containing, besides a variety of oligoanilines named as Aniline Black or Polyaniline, Mauvein as a deeply purple phenazine derivative. Although this Mauvein synthesis was developed by W.H. Perkin more than 150 years ago and has opened the era of industrial dyestuff chemi...

The ability of some bacteria and filamentous fungi to degrade aniline and its derivatives was reported earlier in the literature. However, there was no information about the biodegradation of aniline by yeast strains. The present work is focused on yeast strain Candida methanosorbosa BP-6 which was isolated from the wastewater pool of the old dye factory "Boruta" in Zgierz by enrichment techniq...

A small set of unsymmetrically substituted acene derivatives containing either aniline or dithiocarbamate moieties was synthesized. A stepwise, one-pot procedure was used to transform appropriate acenequinones to aniline-linked acenes in one step with moderate yields. A heretofore-unreported carbon disulfide activation process involving the formation of a trialkylammonium dithiocarbamate interm...

Mannich reaction was applied between 4-fluorobezaldehyde, selected acetophenone and several anilines, catalyzed by silica sulfuric acid for the synthesis of β-amino carbonyl derivatives. Reaction time and yield of the products depended on the nature of acetophenone and aniline subsituents. Using aliphatic amines instead of aromatic amines under same reaction conditions, afforded aldol condensat...
