A highly convenient method has been developed for the synthesis of (prop-2-ynyloxy) benzene and its derivatives. Differently substituted phenol and aniline derivatives were allowed to react with propargyl bromide in the presence of K2CO3 base and acetone as solvent. The compounds were synthesized in good yields (53-85%). Low cost, high yields and easy availability of compounds helped in the syn...

Structure-activity relationship studies of diaryl amine-type KSP inhibitors were carried out. Diaryl amine derivatives with a pyridine ring or urea group were less active when compared with the parent carboline and carbazole derivatives. Optimization studies of a lactam-fused diphenylamine-type KSP inhibitor revealed that the aniline NH group and 3-CF3 phenyl group were indispensable for potent...

The reaction of 2,4-difluoronitrobenzene with an excess aniline at 175 °C led to the isolation unexpected brown quinone substituted two phenylamino groups and one phenylimino group. This product was easily distinguished from other expected derivatives because it is rather than yellow. UV/Vis has a weak long wavelength absorption 480–600 nm accounting for colour.

An oxidative sequence for the conversion of oxindoles to structurally distinct heterocyclic scaffolds and aniline derivatives is disclosed by the combination of a copper-catalyzed C-H peroxidation and subsequent base-mediated fragmentation reaction. In contrast to classic enzymatic (i.e., kynurenine pathway) and biomimetic methods (i.e., Witkop-Winterfeldt oxidation) for oxidative indole cleava...

A number of N-arylmethyl substituted indole derivatives have been synthesized and their effectiveness against ADP and arachidonic acid induced platelet aggregation in human plasma was determined. The desired compounds were synthesized by reacting the appropriate aniline derivative with isatin (or substituted isatin) to form the corresponding imine structures. The so formed compound was then act...

The reduction of nitroarenes to anilines as well azobenzenes hydrazobenzenes using a single base-metal catalyst is reported. hydrogenation reactions are performed with an air-and moisture-stable manganese and proceed under relatively mild reaction conditions. transformation tolerates broad range functional groups, affording aniline derivatives in high yields. Mechanistic studies suggest that th...
