Zanthoxylum simulans Hance, commonly known as Sichuan pepper, is a well-known medicinal plant recognized for its potential as a source of bioactive specialized metabolites. As part of our interest in natural antifungal compounds, the present study de...
An unsymmetrical PCN palladium pincer complex 2-{(E)-{{(R)-1-[(1R,5S,6R)-3,3-dimethyl-2,4,7-trioxabicyclo[3.3.0]octan-6-yl]ethyl}imino}methyl}-6-{[(diphenylphosphino)oxy] phenyl}palladium(II) chloride based on an iminophosphinite ligand bearing two f...
New phenylacetic acid derivatives with potentially valuable biological activities and the ability to act as starting materials for various functionalizations have been prepared by a multi-step synthesis. Starting from 2,6-dibromo-4-methylaniline, the...
The synthesis of a new tetracationic porphyrin derivative is described. Contrary to the best known derivatives in the literature, which are derived from 5,10,15,20-tetrakis-4-pyridylporphyrin (TPyP), in this procedure we start from 5,10,15,20-tetraki...
(S)-1-Methyl-2-oxoimidazolidine-4-carboxylic acid 1 is an analog of (S)-pyroglutamic acid, a key component of naturally occurring peptide hormones and synthetic pharmaceutical candidates. The reaction of (S)-2-amino-3-(methylamino)propionic acid with...
In this study, [(N-benzamidomethyl)(N-benzoyl)amino]methyltriphenylphosphonium tetrafluoroborate was synthesized at 80 °C, starting from N-benzoylaminomethyltriphenylphosphonium tetrafluoroborate, by a specific α-amidoalkylation reaction us...
A novel single-step method has been developed for the synthesis of 1-(1-isocyanoethyl)adamantane from 1-(1-adamantylethyl)amine, chloroform, and t-BuOK, in a dichloromethane/tert-butanol (1:1) medium, yielding 92%, which is 27% higher compared to the...
A highly reactive dicuprate/CuCl aggregate, Nap(Cu4Cl2)(TMEDA)2 (2, Nap = naphthalene-1,8-diyl, TMEDA = tetramethylethylenediamine), was synthesized by the reaction of 1,8-dilithionaphthalene(TMEDA)2 with four equivalents of CuCl. The X-ray crystal s...
We report a one-step synthesis of trifluoromethyl-substituted di(pyridin-2-yl)amine-based ligands. N-(hetero)aryl-substituted bis(5-(trifluoromethyl)pyridin-2-yl)amines were obtained from 2-bromo-5-(trifluoromethyl)pyridine and corresponding aromatic...
In this study, we report the synthesis of (±)-2-chloro-N-(4-methyl-2-oxo-2H-chromen-7-yl)-2-phenylacetamide through the reaction of 7-amino-4-methyl-2H-chromen-2-one with (±)-2-chloro-2-phenylacetyl chloride. The in vitro anti-inflammat...
