A derivative of dihydrotetrazolopyrimidine has been successfully synthesized through a cyclocondensation reaction between a chalcone derivative with 5-aminotetrazole. The molecular structure of the title compound was established based on Fourier tran...
The X-ray structure of the title compound contains eight molecules in the unit cell which form the basis of a herringbone arrangement of hydrogen bonded ribbons.
1-(2-Hydroxyethyl)imidazolidine-2-thione (1) was obtained as a product from an in situ reaction between N-(2-hydroxyethyl)ethylenediamine, carbon disulfide, potassium hydroxide, and di(4-fluorobenzyl)tin dichloride. Compound 1 was characterized by IR...
N′-(4-Methoxybenzylidene)-5-methyl-1-phenyl-1H-1,2,3-triazole-4-carbohydrazide (3) was synthesized in a yield of 88% from an acid-catalyzed reaction of 5-methyl-1-phenyl-1H-1,2,3- triazole-4-carbohydrazide and 4-methoxybenzaldehyde in ethanol u...
A series of ureido derivatives of neoabietic acid were synthesized by application of Curtius rearrangement reaction to neoabietic acid and amines. Structure characterization of these compounds was done by 1H-NMR, 13C-NMR and HRMS spectral analysis.
The new ligand 4′-(5-methylfuran-2-yl)-2,2′:6′,2″-terpyridine (1) was prepared in one step from 2-acetylpyridine and 5-methylfurfural. The latter is an aldehyde that can be readily obtained from biomass. The new terpyridine mo...
The compound in the title was prepared by reaction between tryptamine and ibuprofen using N,N′-dicyclohexylcarbodiimide as a “dehydrating” reagent. The structure of the newly synthesized compound was determined by nuclear magnetic r...
N-[4-(1-Methyl-1H-imidazol-2-yl)-2,4′-bipyridin-2′-yl]benzene-1,4-diamine was synthesized with a good yield by the reaction of 2′-chloro-4-(1-methyl-1H-imidazol-2-yl)-2,4′-bipyridine with 4-phenylenediamine. The functionalization of the pyridine was...
The Biginelli reaction is a highly versatile reaction that leads to dihydropyrimidinones/thiones. This scaffold is reported as being a privileged structure due to its ability to interact with biological targets. Synthesis of ethyl 4-(2-fluorophenyl)-...
