We have explored the reactions of tetrahydro-4H-selenochromenes in the presence of phosphoric pentachloride, and synthesized new condensate aroylbenzoselenophenes. During the reactions, tetrahydro-4H-selenochromenes with phosphoric pentachloride underwent oxidative aromatization and nucleophilic substitution for a chlorine atom of one of the protons in the alicyclic fragment. Also, the narrowing of the heterocyclic fr Read More

Perimidines are peri-naphtho-fused derivatives of pyrimidine. They are of particular interest as they are a rare example of an azine in which the lone pair of electrons of pyrrole-like nitrogen participates in the π-system of the molecule. Perimidine is an interesting class of heterocyclic compounds. Various synthetic analogs of perimidines have been prepared and evaluated for many pharmacological activities in differen Read More

The search for novel nucleosides has been a major research focus in medicinal chemistry for several decades, particularly given their proven track record in the treatment of viral infections and cancer. As bioisosteres of natural nucleosides, thionucleosides are especially attractive targets as they often display improved biological activity. Furthermore, the replacement of oxygen with sulfur may sometimes be accompanied by i Read More

Ionic liquids can be utilized in petroleum science. However, significant attention has been paid to the utilization of ionic liquids in petroleum science by researchers. In this work, the recent development of the utilization of ionic liquids in petroleum science is introduced. First of all, ionic liquids can be utilized as an additive in the oil & gas industry, such as a surfactant, corrosion inhibitor, demulsifier, and dispersant. In addition, ionic l Read More

Achieving challenging molecular diversity in contemporary chemical synthesis remains a formidable hurdle, particularly in the delivery of diversified bioactive heterocyclic pharmacophores for drug design and pharmaceutical applications. The coupling methods that combine a diverse range of readily accessible and commercially available pools of substrates under the action of earth-abundant first row transition metal catalysts Read More
