We have developed a new series of simple biaryl piperidine derivatives (11–19) based on biaryl naphthylisoquinoline alkaloid Ealamine-A. The target compounds were synthesized, analyzed by spectral data, and evaluated for antileishmanial activity against Leishmania donovani strain Ag83 by MTT assay. The compounds have shown the best to moderate antileishmanial activity. The 5′-fluoro-2′-methoxyphenyl derivative 14 and 3′,5′-difluorophenyl derivative 16 have inhibited the promastigotes by 86 % and 85 % after 24 h and 92 % and 91 % after 48 h incubation, respectively, at 400 μM concentration. The % inhibition was lower with the lowering of the concentration and increased with the incubation time. Compounds 12, 15, and 18 have solubility issues and proved to be less active than the rest of the compounds. Molecular docking studies were performed on selective active compounds and the results indicate that these compounds may act by binding to the Leishmanolysin and the docking scores are in good correlation with the antileishmanial activity. These results provide an initial insight into the design of new therapeutics for neglected tropical diseases.

Copper-catalyzed alkene amino oxygenation reactions using O-acylhydroxylamines have been achieved for a rapid and modular access to diverse 1,2-amino oxygen-containing molecules. This transformation is applicable to the use of alcohols, carbonyls, oximes, and thio-carboxylic acids as nucleophiles on both terminal and internal alkenes. Mild reaction conditions tolerate a wide range of functional groups, including ether, ester, amide, carbamate, and halide. The reaction protocol allows for starting with free amines as the precursor of O-benzoylhydroxylamines to eliminate their isolation and purification, contributing to broader synthetic utilities. Mechanistic investigations reveal the amino oxygenation reactions may involve distinct pathways, depending on different oxygen nucleophiles.
