Quinoxalines belong to a class of excellent heterocyclic scaffolds owing to their wide biological properties and diverse therapeutic applications in medicinal research. They are complementary in shapes and charges to numerous biomolecules they interact with, thereby resulting in increased binding affinity. The pharmacokinetic properties of drugs bearing quinoxaline cores have shown them to be relatively easy to administer either as intramuscular solutions, oral capsules or rectal suppositories. This work deals with recent advances in the synthesis and pharmacological diversities of quinoxaline motifs which might pave ways for novel drugs development.

New Advances in Chemical Research in 2021. In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 148231-12-3, name is 5,8-Dibromoquinoxaline, introducing its new discovery. Product Details of 148231-12-3

Four D-A-pi-A motif organic sensitizers (IQ9, IQ10, IQ11 and IQ12) in the absence or presence of thiophene substituents grafted onto the auxiliary acceptor of a quinoxaline unit have been developed for dye sensitized solar cells (DSSCs). Upon changing the pi-linker from benzene to thiophene, the photocurrent (Jsc) of IQ10 increases around 2-fold, and the photovoltage (Voc) decreases by 52 mV compared to that of IQ9. It is attributed to the fact that compared with the benzene linker, the thiophene conjugated bridge in dye IQ10 induces a small twist in the molecular planarity, thus resulting in the high light-harvesting capability (beneficial to Jsc) and high charge recombination (unbeneficial to Voc). To prevent this “trade-off” effect between photocurrent and photovoltage, the building block of 2,3-dithienylquinoxaline as an auxiliary unit is specifically incorporated, which brings forth several advantages such as distinctly extending the light-harvesting region, increasing molar absorption coefficients, and blocking the dye self-aggregation to reduce charge recombination. Remarkably, dye IQ12 exhibits a beneficial balance between Jsc (17.97 mA cm-2) and Voc (715 mV), along with a promising photovoltaic efficiency of 8.76%, much better than the corresponding dyes IQ9 (2.91%), IQ10 (7.75%) and IQ11 (6.56%). As demonstrated, the two twisted thiophene groups grafted onto the quinoxaline unit facilitate the resulting compact sensitizer layer to effectively overcome the charge recombination drawbacks in Voc arising from the thiophene pi-bridge linker, providing a rational molecular engineering to pursue the synergistic enhancement in the photocurrent and photovoltage for highly efficient organic sensitizers.

An investigation employing the catalytic system consisting of (pentamethylcyclopentadienyl)rhodium dichloride dimer [Cp?RhCl2]2 and 2,2?-bipyridine (bpy) for transfer hydrogenation of a variety of quinoxalines, quinoxalinones, quinolines and indoles under aqueous conditions with formate as the hydrogen source is reported. This approach provides various tetrahydroquinoxalines, dihydroquinoxalinones, tetrahydroquinolines and indolines in good to excellent yields. The activity of the catalyst towards quinoxalines and quinoxalinones is excellent, with a substrate to catalyst ratio (S/C) of 10000 being feasible. The choice of ligand is critical to the catalysis, and the aqueous phase reduction is shown to be highly pH-dependent, with acidic pH values needed for optimal reduction. The catalyst is easy to access, and the reaction is operationally simple without requiring an inert atmosphere.
