Abstract The direct functionalization of quinones has always fascinated research communities due to their biological and redox activities subsequent application. Quinone motifs play a vital role as precursors for many bioactive compounds materials; hence, ingenious methodologies have been elaborated exploring these units. A significant part the synthetic strategies towards functionalized achieved by installing substituents on hydroquinones, phenols, or quinone itself different oxidative coupling reactions via radical pathways with without utilization metal catalysts. simple C−H bond remains challenging inherited electronic nature high dissociation energy. This review article summarizes recent advancement made through quinones. Our primary focus will be approaches mechanistic that appeared in last two decades, along short historical importance family.

Given the crucial roles of carbohydrates in energy supply, biochemical processes, signaling events and pathogenesis several diseases, development carbohydrate analogues, called glycomimetics, is a key research area Glycobiology, Pharmacology, Medicinal Chemistry. Among many structural transformations explored, replacement endo- exocyclic oxygen atoms by carbon (carbasugars) or heteroatoms, such as nitrogen (aza- iminosugars), phosphorous (phosphasugars), sulfur (thiosugars), selenium (selenosugars) tellurium (tellurosugars) have garnered significant attention. These isosteric substitutions can modulate bioavailability, stability, bioactivity, while introducing new properties, redox activity, interactions with pathological lectins enzymes, cytotoxic effects. In this manuscript we focused on three major families glycomimetics: thio-, seleno-, tellurosugars. We provide comprehensive review most relevant synthetic pathways leading to primarily at endocyclic glycosidic positions. The scope includes metal-catalyzed reactions, organocatalysis, electro- photochemical transformations, free-radical automated syntheses. Additionally, mechanistic insights, stereoselectivity, biological properties are also discussed. diversity promising bioactivities these glycomimetics underscore their significance area.

Abstract Tellurium is now recognized as a ‘technology-critical element’ that quickly being used in innovative applications. The chemistry of organotellurium ligands has improved rapidly during the last three decades. Because their enhanced accessibility and possibility they would display significantly different properties than sulfur counterparts, these heavier chalcogens have sparked considerable attention. next sections will go through various tellurium associated transition-metal complexes. Organochalcogen are exceedingly flexible may react with nearly any transition metal to form wide range compounds, including multidentate ligands.Tellurides metals lately been investigated for potential use storage devices, solar cells, piezoelectric, medical applications, electronics, photothermal treatment, nanoplatelets, nanocrystals, catalysis, other fields. Researchers interested chalcogenide heterostructures because charge transport synergistic optoelectronic catalytic properties. A sensor based on Te electrodes donor ligand generate electrical signals identify metals.

Abstract A highly efficient new protocol has been developed for the formation of C−Te bonds, leading to both symmetrical and unsymmetrical diaryl tellurides. This utilizes sodium aryltellurites ( 4 ), which can be easily prepared from low‐cost aryltelluride trichlorides NaOH. The synthesis involves use arylazo sulfones as starting materials in presence (MeO) 2 P(O)H. variety tellurides are obtained moderate good yields using this method. Importantly, innovative eliminates need traditional, toxic aryltellurolating reagents such ditellurides elemental tellurium. study will bring vitality
