Umpolung was a unique strategy which converts the property of an atom into the opposite one. An efficient and general method for the construction of quinoline N-oxides I [R = Me, Ph, 2-pyridyl, etc.; R1 = 6-F, 6-Br, 6,7-di-OMe, etc.] via umpolung of carbonyl groups was developed from ortho-nitro chalcones and hydrazine in basic conditions. The strategy was transition-metal free and had good functional group tolerance, environmental friendliness, as well as mild reaction conditions with nitrogen gas as the byproduct.

Dong, Xiao-Yang’s team published research in Angewandte Chemie, International Edition in 2021-01-25 | CAS: 1468-83-3

Angewandte Chemie, International Edition published new progress about Alkynes, α- Role: RCT (Reactant), RACT (Reactant or Reagent). 1468-83-3 belongs to class benzothiophene, name is 3-Acetylthiophene, and the molecular formula is C6H6OS, Synthetic Route of 1468-83-3.

Dong, Xiao-Yang published the artcileCopper-Catalyzed Asymmetric Coupling of Allenyl Radicals with Terminal Alkynes to Access Tetrasubstituted Allenes, Synthetic Route of 1468-83-3, the main research area is enyne alkyne alkyl bromide copper carboalkynylation catalyst; allene stereoselective preparation; 1,4-enynes; alkyl bromides; allenes; asymmetric radical reactions; copper.

In contrast to the wealth of asym. transformations for generating central chirality from alkyl radicals, the enantiocontrol over the allenyl radicals for forging axial chirality represents an uncharted domain. The challenge arises from the unique elongated linear configuration of the allenyl radicals that necessitates the stereo-differentiation of remote motifs away from the radical reaction site. We herein describe a copper-catalyzed asym. radical 1,4-carboalkynylation of 1,3-enynes via the coupling of allenyl radicals with terminal alkynes, providing diverse synthetically challenging tetrasubstituted chiral allenes. A chiral N,N,P-ligand is crucial for both the reaction initiation and the enantiocontrol over the highly reactive allenyl radicals. The reaction features a broad substrate scope, covering a variety of (hetero)aryl and alkyl alkynes and 1,3-enynes as well as radical precursors with excellent functional group tolerance.

On March 31, 2011, Pinson, Jo-Anne; Schmidt-Kittler, Oleg; Zhu, Jiuxiang; Jennings, Ian G.; Kinzler, Kenneth W.; Vogelstein, Bert; Chalmers, David K.; Thompson, Philip E. published an article.Related Products of 16296-68-7 The title of the article was Thiazolidinedione-Based PI3Kα Inhibitors: An Analysis of Biochemical and Virtual Screening Methods. And the article contained the following:

A series of synthesized and com. available compounds were assessed against PI3Kα for in vitro inhibitory activity and the results compared to binding calculated in silico. Using published crystal structures of PI3Kγ and PI3Kδ co-crystallized with inhibitors as a template, docking was able to identify the majority of potent inhibitors from a decoy set of 1000 compounds On the other hand, PI3Kα in the apo-form, modeled by induced fit docking, or built as a homol. model gave only poor results. A PI3Kα homol. model derived from a ligand-bound PI3Kδ crystal structure was developed that has a good ability to identify active compounds The docking results identified binding poses for active compounds that differ from those identified to date and can contribute to our understanding of structure-activity relationships for PI3K inhibitors. The experimental process involved the reaction of 5-Chlorobenzo[b]thiophene-3-carbaldehyde(cas: 16296-68-7).Related Products of 16296-68-7
