A scalable and operationally simple decarboxylative trifluoromethylation of (hetero)arenes with easily accessible C6F5I(OCOCF3)2 under photoredox catalysis has been developed. This method is tolerant of various (hetero)arenes and functional groups. Notably, C6F5I is recycled from the decarboxylation reaction and further used for the preparation of C6F5I(OCOCF3)2. The combination of photoredox catalysis and hypervalent iodine reagent provides a practical approach for the application of trifluoroacetic acid in trifluoromethylation reactions.

(Figure Presented) Reduction on imine moiety (C=N) of quinoxalines by alkyl-/aryllithiums led to a geometrical change on the quinoxaline ring, thereby perturbing the electronic structure to turn on fluorescence emission. Such a structural change resulted in interrupted cyclic-ring systems with electron-donating amine (sp3-type) and electron-accepting imine (sp2-type) units bridged by a phenylene unit. Through either alkylation or arylation, a highly polarized electron donor-electron acceptor bipolar system was established in a single molecule with dramatically enhanced PL efficiency (up to 60%).

(Chemical Equation Presented) Four chiral diphosphine ligands consisting of bis(2,5-diphenylphospholan-1-yl) groups connected by the sp2 carbon linkers 2,3-quinoxaline ((S,S)-Ph-Quinox), 2,3-pyrazine ((S,S)-Ph-Pyrazine), maleic anhydride ((S,S)-Ph-MalPhos), and 1,1?-ferrocene ((S,S)-Ph-5-Fc) were synthesized, and their cationic [rhodium-(I)(COD)] complexes were prepared. These complexes were tested in asymmetric hydrogenation of functionalized olefins. [((S,S)-Ph-Quinox)Rh(COD)]BF4 showed high activity and selectivity against itaconate and dehydroamino acid substrates. The corresponding (S,S)-Ph-Pyrazine and (S,S)-Ph-MalPhOS complexes exhibited lower activities and selectivities. [((S,S)-Ph-S-Fc)Rh(COD)]BF4 showed high activity with low selectivity for these substrates, but high activity and selectivity against 2-C-substituted cinnamate salts, whereas rhodium complexes of (S,S)-Ph-Quinox and (R,R)-Ph-BPE showed low activity and selectivity against 2-C-substituted cinnamate salts.

Some heterocyclic systems namely cholest-5-en-7-thiazolo[4,5-b]quinoxaline-2-yl-hydrazone] were synthesized by the reaction of cholest-5-en-7-one-thiosemicarbazone with 2,3-dichloroquinoxaline at 80 C in high yield. The thiosemicarbazone derivatives were obtained by the condensation of the thiosemicarbazide with steroidal ketones. All the compounds have been characterized by means of elemental analyses, IR, 1H NMR and mass spectroscopic data. The in vitro antibacterial activity was evaluated by disk diffusion method and then the minimum inhibitory concentration (MIC) of compounds was determined against the culture of Escherichia coli. The results were compared with the standard drug chloramphenicol. The results showed that compounds 7 and 8 are better antibacterial agents as compared to chloramphenicol.

An inexpensive, practical and one-pot method has been developed for the synthesis of quinoxalines fused with pyrano[3,4-b]indole, the central core of Lamellarin D. The methodology involved construction of the central pyranone ring via an AlCl3-mediated heteroarylation-cyclization method. A number of compounds were prepared using this methodology, some of which were converted to the corresponding indol-3-ylquinoxaline derivatives. Several of the pyrano[3,4-b]indole fused quinoxalines showed promising growth inhibition of cervical and lung cancer cells and good interactions with topoisomerase I in silico.
