On August 31, 2018, Laha, Joydev K.; Patel, Ketul V.; Tummalapalli, K. S. Satyanarayana; Hunjan, Mandeep Kaur published an article.Recommanded Product: 685-91-6 The title of the article was Palladium-Catalyzed Serendipitous Synthesis of Arylglyoxylic Amides from Arylglyoxylates and N,N-Dialkylamides in the Presence of Halopyridines. And the article contained the following:

A palladium-catalyzed synthesis of arylglyoxylic amides by the reaction of arylglyoxylates and N,N-dialkylamides in the presence of a 2,3-dihalopyridine has been realized for the first time. An anticipated 2,3-diaroylpyridine did not form in this reaction. The current study unveils an unprecedented role of 2,3-dihalopyridine toward this amidation. Our mechanistic study reveals that the arylglyoxylate could react with halopyridine to form a traceless activated pyridyl ester of arylglyoxylic acid, which upon subsequent reaction with amino surrogate, N,N-dialkylamides could form the arylglyoxylic amides. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Recommanded Product: 685-91-6

The Article related to arylglyoxylate dialkylamide dihalopyridine palladium amidation catalyst, arylglyoxylic amide preparation, Benzene, Its Derivatives, and Condensed Benzenoid Compounds: Amides, Amidines, Imidic Esters, Hydrazides, and Hydrazonic Esters and other aspects.Recommanded Product: 685-91-6

On December 4, 2020, Lv, Ningning; Yu, Shuling; Hong, Chao; Han, De-Man; Zhang, Yuhong published an article.Quality Control of N,N-Diethylacetamide The title of the article was Selectively Oxidative C(sp2)-H/C(sp3)-H Cross-Coupling of Benzamides with Amides by Nickel Catalysis. And the article contained the following:

The oxidative cross-coupling between the α-C(sp3)-H bond of amide in DMAc and the inert ortho-C(sp2)-H bond of benzamides is achieved for the first time by nickel catalysis, with the assistance of 8-aminoquinolyl group in the presence of a silver oxidant. Notably, the selectivity of conversion can be perfectly controlled by modulating the oxidant additives, and the products from the coupling of the C(sp3)-H bond adjacent to nitrogen of amides with benzamides are approached through the use of peroxide. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Quality Control of N,N-Diethylacetamide

On January 1, 2021, Gu, Xiaoke; Zhang, Yinpeng; Zou, Yueting; Li, Xin; Guan, Mingyu; Zhou, Qingqing; Qiu, Jingying published an article.Electric Literature of 27115-50-0 The title of the article was Synthesis and evaluation of new phenyl acrylamide derivatives as potent non-nucleoside anti-HBV agents. And the article contained the following:

As a continuation of our previous work, a series of new Ph acrylamide derivatives were designed and synthesized as non-nucleoside anti-HBV agents. Among them, compound I could potently inhibit HBV DNA replication in wild-type and lamivudine (3TC)/entecavir resistant HBV mutant strains with IC50 values of 0.19 and 0.18μM, resp. Notably, the selective index value of I was above 526, indicating the favorable safety profile. Interestingly, unlike nucleoside analog 3TC, I could significantly inhibit 3.5 kb pgRNA expression. Mol. docking study revealed that I could fit well into the dimer-dimer interface of HBV core protein by hydrophobic, π-π and H-bond interactions. Considering the potent anti-HBV activity, low toxicity and diverse anti-HBV mechanism from that of nucleoside anti-HBV agent 3TC, compound I might be a promising lead to develop novel non-nucleoside anti-HBV therapeutic agents, and warranted further investigation. The experimental process involved the reaction of 2-(4-Methylbenzamido)acetic acid(cas: 27115-50-0).Electric Literature of 27115-50-0

A series of catalysts based on supported copper nanoparticles were prepared and tested in the amide bond formation from tertiary amines and acid anhydrides, in the presence of tert-Bu hydroperoxide as an oxidant. Copper nanoparticles on zeolite Y (CuNPs/ZY) was found to be the most efficient catalyst for the synthesis of amides, working in acetonitrile as solvent, under ligand- and base-free conditions in air. The products were obtained in good to excellent yields and in short reaction times. The CuNPs/ZY system also exhibited higher catalytic activity than some com. available copper and iron sources and it was reused in ten reaction cycles without any further pre-treatment. This methodol. was successfully scaled-up to a gram scale with no detriment to the yield.
