The S8/DMSO combination was found to be particularly effective promote oxidative coupling of methylhetarenes with amines synthesize thioamides/bis-aza-heterocycles.

Despite the importance of stacking interactions between ligands and aromatic amino acid side chains in binding sites, it is still unclear how such can be optimized context design. I will present highly-accurate computed interaction energies for parallel stacked dimers pharmaceutically relevant heterocycles. The trends that are observed described using a combination known descriptors dispersion ...

the heterocyclic compounds have a great importance in medicinal chemistry. one of the most important heterocycles in medicinal chemistry are quinazolines possessing wide spectrum of biological properties like antibacterial, antifungal, anticonvulsant, anti-inflammatory, anti-hiv, anticancer and analgesic activities. this skeleton is an important pharmacophore considered as a privileged structur...

An automated continuous flow and real-time analytics platform facilitates the generation of quantitative data to understand sensitivity reaction performance in presence different functional groups heterocycles.

Nitrogen containing heterocyclic compounds have great utility in synthetic, medicinal and material chemistry. Oxazole, isoxazole, thiazole, imidazole their derivatives gained prominence as they constitute the structural features of many bioactive compounds. In fact, amide functionality represents a privileged scaffold biomolecules drugs. The combination two or more heterocycles linked by into o...

[Reaction: see text]. Nitrogen heterocycles are present in many compounds of enormous practical importance, ranging from pharmaceutical agents and biological probes to electroactive materials. Direct functionalization of nitrogen heterocycles through C-H bond activation constitutes a powerful means of regioselectively introducing a variety of substituents with diverse functional groups onto the...

Heterocyclic compounds are widely prevalent in animal kingdom as well as in plant kingdom and they play various roles in metabolic processes. A large number of heterocyclic compounds are in clinical practice as a drug, while many of them find industrial utility and hence the syntheses of heterocyclic compounds and understanding of the biological importance of specific heterocyclic class will be...

Reaction of Glycin with Malononitrile afforded respective Pyrrole. Pyrrole is one of the heterocyclic compounds with very important biological activities. Heterocycles are extremely important because of their wide range of applications that goes from their use as pharmaceuticals and agrochemicals to dyestuffs and additives. In this view, it was proposed to synthesize pyrrole-3-carbonitrile deri...

Highly enantioselective synthesis of chiral chromenes and tetrahydroquinolines is achieved by combining asymmetric copper-catalyzed allylic substitution with Grignard reagents and an efficient intramolecular Heck reaction. Moreover, the exocyclic double bond formed in the cyclisation was subjected to RCM, hydroboration and hydrogenation illuminating the synthetic versatility of these heterocycles.

Magnetic nanoparticle-supported proline ligand was prepared and used for the CuI catalyzed Ullmann-type coupling reactions of aryl/heteroaryl bromides with various nitrogen heterocycles to form the corresponding N-aryl products in good to excellent yields; furthermore, this magnetic nanoparticle-supported proline ligand could be readily separated using an external magnet and reused without sign...
