Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Begam, HM; Choudhury, R; Behera, A; Jana, R. The CAS is 90-27-7. Through research, I have a further understanding and discovery of 2-Phenylbutanoic acid. Product Details of 90-27-7

A practical copper-catalyzed, 2-picolinamide-directed ortho C-H amination of anilines with benzoyl protected hydroxylamines has been disclosed that proceeds smoothly without any external stoichiometric oxidant or additives. Remarkably, besides anilines, bicyclic naphthyl or heterocyclic amines furnished amination products with five and six-membered cyclic and acyclic amines at the ortho position selectively. This electrophilic C-H amination also proceeds smoothly in water under slightly modified reaction conditions.

An efficient reactive system was established to produce (S)-2-phenylbutyric acid (2-PBA) through the enzymatic enantioselective hydrolysis of 2-phenylbutyrate ester (2-PBAE) in aqueous medium. Lipase CALA from Canadian antarctica and hexyl 2-phenylbutyrate (2-PBAHE) were identified upon screening as the best enzyme and substrate, respectively. Adding hydroxyethyl-beta-cyclodextrin (HE-beta-CD) to improve the solubility of the substrate resulted in a 1.5 times increase in substrate conversion while retaining a high enantioselectivity compared with that when HE-beta-CD was not added. The effects of lipase concentration, substrate concentration and HE-beta-CD concentration, temperature, pH, and reaction time on enantiomeric excess and conversion rate were investigated, and the optimal conditions were identified using response surface methodology (RSM). Under the optimal conditions, namely 50 mg/mL lipase CALA, 30 mmol/L substrate, 60 mmol/L HE-beta-CD, pH of 6.5, temperature of 83 degrees C and reaction time of 18 h, the enantiomeric excess and overall conversion rate were 96.05% and 27.28%, respectively. This work provides an efficient alternative method for improving the conversion of aromatic ester substrates by including beta-cyclodextrin in an aqueous hydrolysis reaction system.

An article Deracemizing alpha-Branched Carboxylic Acids by Catalytic Asymmetric Protonation of Bis-Silyl Ketene Acetals with Water or Methanol WOS:000475080500001 published article about PRACTICAL CHIRAL AUXILIARY; ENANTIOSELECTIVE PROTONATION; BRONSTED ACID; DISILYL ACETALS; ENOL ETHERS; ALKYLATION; PSEUDOEPHEDRINE; GENERATION; ALDEHYDES in [Mandrelli, Francesca; Blond, Aurelie; James, Thomas; Kim, Hyejin; List, Benjamin] Max Planck Inst Kohlenforsch, Kaiser Wilhelm Pl 1, D-45470 Mulheim, Germany in 2019, Cited 52. Application In Synthesis of 2-Phenylbutanoic acid. The Name is 2-Phenylbutanoic acid. Through research, I have a further understanding and discovery of 90-27-7

We report a highly enantioselective catalytic protonation of bis-silyl ketene acetals. Our method delivers alpha-branched carboxylic acids, including nonsteroidal anti-inflammatory arylpropionic acids such as Ibuprofen, in high enantiomeric purity and high yields. The process can be incorporated in an overall deracemization of alpha-branched carboxylic acids, involving a double deprotonation and silylation followed by the catalytic asymmetric protonation.

Application In Synthesis of 2-Phenylbutanoic acid. Bye, fridends, I hope you can learn more about C10H12O2, If you have any questions, you can browse other blog as well. See you lster.

Triazolopyridinone derivatives are of high value in both medicinal and material chemistry. However, the chiral or hindered triazolopyridinone derivatives remain an underexplored area of chemical space because they are difficult to prepare via conventional methods. Here we report an electrochemical rearrangement for the efficient synthesis of otherwise inaccessible triazolopyridinones with diverse alkyl carboxylic acids as starting materials. This enables the efficient preparation of more than 60 functionalized triazolopyridinones under mild conditions in a sustainable manner. This method is evaluated for the late stage modification of bioactive natural products, amino acids and pharmaceuticals, and it is further applied to the decagram scale preparation of enantiopure triazolopyridinones. The control experiments support a mechanism involving an oxidative cyclization and 1,2-carbon migration. This facile and scalable rearrangement demonstrates the power of electrochemical synthesis to access otherwise-inaccessible triazolopyridinones and may find wide application in organic, material and medicinal chemistry. Chiral and hindered triazolopyridinone derivatives are an underexplored area of chemical space mainly due to their challenging synthesis via classical methods. Here, the authors report an electrochemical rearrangement for the synthesis of triazolopyridinones using diverse, available alkyl carboxylic acids as starting materials.
