Xiao, Yan published the artcileRhodium-Catalyzed Reaction of Azobenzenes and Nitrosoarenes toward Phenazines, SDS of cas: 1885-29-6, the main research area is azobenzene nitrosoarene rhodium annulation catalyst; phenazine preparation.

A rhodium-catalyzed annulative reaction between azobenzenes and nitrosoarenes has been developed, leading to a series of phenazines I (R1 = H, 2-Cl, 2-MeO, 2-Me, etc.; R2 = H, 2-Me, 2-t-Bu, 2-Br, etc.) in moderate to good yields. This procedure proceeds with sequential chelation-assisted addition of aryl C-H to nitrosoarenes and ring closure by electrophilic attack of azo group to aryl. During this transformation, the azo group served as not only a traceless directing group but also a building block in the final products.

Geigle, Stefanie N. published the artcileDevelopment of DNA-Compatible Van Leusen Three-Component Imidazole Synthesis, Application In Synthesis of 263389-54-4, the main research area is DNA compatible three component imidazole synthesis.

DNA-encoded libraries (DELs) have generated recent interest due to their ability to provide new small mol. ligands for pharmaceutically important proteins. The chem. diversity of DELs determines their ability to provide potent, novel, and drug-like chem. matter, and DEL chem. diversity is limited by the scope of DNA-compatible chem. reactions. Herein, the one-pot three-component Van Leusen chem. is applied to DEL synthesis, providing the first reported DNA-compatible method to generate novel highly functionalized imidazoles.

Fu, Zhengjiang published the artcileConversions of aryl carboxylic acids into aryl nitriles using multiple types of Cu-mediated decarboxylative cyanation under aerobic conditions, Safety of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is aryl nitrile preparation green chem; malononitrile aryl carboxylic acid decarboxylative cyanation copper catalyst; azodimethylbutyronitrile aryl carboxylic acid decarboxylative cyanation copper catalyst.

Here, used malononitrile or AMBN as a cyanating agent to develop efficient and practical protocols for Cu-mediated decarboxylative cyanations, under aerobic conditions, of aryl carboxylic acids RC(O)OH (R = 2-nitrophenyl, 2,4,6-trimethoxyphenyl, 3-methyl-1-benzothiophen-2-yl, etc.) bearing nitro and methoxyl substituents at the ortho position as well as of heteroaromatic carboxylic acids. These protocols involved economical methods to synthesize value-added aryl nitriles RCN from simple and inexpensive raw materials. Further diversification of the 2-nitrobenzonitrile product was performed to highlight the practicality of the protocols.

Fukazawa, Yasuaki published the artcileA Mild Method for Electrochemical Reduction of Heterocyclic N-Oxides, Related Products of nitriles-buliding-blocks, the main research area is electrochem reduction heterocyclic amine oxide.

Deoxygenation of heteroaromatic N-oxides is commonly accomplished using chem. or enzymic methods. In this work, we report on an expedient protocol for electrochem. reduction of pyridine N-oxide derivatives under mild conditions. A diverse range of mono- and bis N-oxides were converted into the corresponding nitrogen bases in good yields. Importantly, the method is highly selective towards N-oxides and tolerates challenging halo and nitro substituents in the heteroaromatic ring. Thus, e.g., 2-phenylpyridine N-oxide �2-phenylpyridine (89% isolated) by carring out the reaction in an undivided electrochem. cell with two graphite electrodes in 1:1 MeCN/water mixture using LiBF4 as supporting electrolyte.

A readily available and highly modular class of chiral P,N,N-ligands based on a structurally flexible nonchiral phosphine-amine framework with an optically active 1,2-diphenylethylenediamine unit bearing a tertiary amine terminus as the chiral source were developed and successfully applied in the Ir-catalyzed asym. hydrogenation of o-amidophenyl ketones. These tridentate P,N,N-ligands exhibited excellent activity, enantioselectivity, and substrate tolerance, thus furnishing various optically active o-amidobenzhydrols in up to 99% yields and with >99% ee. The utility of this protocol was proven by synthetically diverse product transformation and highly enantioselective production of a rice plant growth regulator, (S)-inabenfide.
