Ruzi, Rehanguli published the artcileDeoxygenative Arylation of Carboxylic Acids by Aryl Migration, Recommanded Product: Coumarin-6-sulfonyl chloride, the publication is Chemistry – A European Journal (2019), 25(55), 12724-12729, database is CAplus and MEDLINE.

An unprecedented deoxygenative arylation of aromatic carboxylic acids was achieved, allowing the construction of an enhanced library of unsym. diaryl ketones. The synergistic photoredox catalysis and phosphoranyl radical chem. allows for precise cleavage of a stronger C-O bond and formation of a weaker C-C bond by 1,5-aryl migration under mild reaction conditions. This new protocol was independent of substrate redox-potential, electronic, and substituent effects. It afforded a general and promising access to 60 examples of synthetically versatile o-amino and o-hydroxy diaryl ketones under redox-neutral conditions. Furthermore, it also brings one concise route to the total synthesis of quinolone alkaloid, (±)-yaequinolone A2, and a viridicatin derivative in satisfying yields.

Hrdina, R. published the artcileIron complexes of reactive azo dyes, Related Products of chlorides-buliding-blocks, the publication is Advances in Colour Science and Technology (2004), 7(1), 6-17, database is CAplus.

A set of reactive mordant azo dyes was prepared by diazotization of aromatic amines and their subsequent coupling reaction with secondary components. The reactive dyes thus formed contained 2-sulfatoethylsulfonyl (-SO₂CH₂CH₂OSO₃Na), N-methyl-N-carboxymethyl-2-aminoethylsulfonyl (-SO₂CH₂CH₂NMeCH₂CO₂H) and 2,3-dibromopropionamidyl (-NHCOCHBrCH₂Br) reactive groups capable of liberating reactive vinyl groups in the application dyebath. Neg.-ion electrospray ionization mass spectrometry, UV/visible spectroscopy, and elemental anal. confirmed the structure of the prepared dyes. Dyed wool fabric samples (combination of acid and reactive dyeing conditions) were treated (mordanted) with iron salts (FeCl₂, FeCl₃) and a comparison chromium salt (CrF₃). The iron mordant dyeing showed acceptable wash fastness and light fastness comparable with chromium complexed dyes.

Luong, Hoa published the artcileImprovement in the One-Carbon Chain Extension of Esters with Dimethylsulfoxonium Methylide, HPLC of Formula: 5034-06-0, the publication is European Journal of Organic Chemistry (2013), 2013(20), 4238-4241, database is CAplus.

A recent report suggests that the reaction of dimethylsulfoxonium methylide with esters does not produce a chain-extended sulfur ylide as previously reported, but rather affords the corresponding carboxylate salt. We have investigated this assertion by using a combination of ab initio MO calculations, spiking studies, and isotopic labeling. The formation of carboxylate is unambiguously demonstrated to arise through hydrolysis involving adventitious water, principally derived from moisture in com. trimethylsulfoxonium chloride. Careful vacuum drying of this reagent diminishes the competing hydrolytic pathway resulting in higher yields for the chain-extension reaction than previously reported.

Wang, Huaimin published the artcileEnzyme-Catalyzed Formation of Supramolecular Hydrogels as Promising Vaccine Adjuvants, Application In Synthesis of 42074-68-0, the publication is Advanced Functional Materials (2016), 26(11), 1822-1829, database is CAplus.

Promising vaccine adjuvants of self-assembling peptide hydrogels for protein ovalbumin (OVA) are introduced in this study. The hydrogels are formed by the enzyme of phosphatase, and the vaccine adjuvant potency of both L– and D-peptide hydrogels is evaluated. The results indicate that, compared with the clin. used alum adjuvant, both L– and D-peptide hydrogels can increase the IgG production of OVA for about 1.3 and 3.8 times, resp. Both gels can enhance antigen uptake and induce dendritic cell maturation, and promote and prolong accumulation of antigen in lymph node, as well as evoke germinal center formation. However, the D-peptide hydrogel with OVA exhibits a slightly more efficient accumulation of OVA in the lymph nodes and seems preventing tumor growth more significantly than its L-counterpart. With the good biocompatibility and degradability of peptide hydrogels, the hydrogels described in this study have big potential for the production of protein vaccines for immunotherapy against different diseases.

Dong, Huan published the artcileSynthesis and properties of tetraphenylethylene derivatived diarylethene with photochromism and aggregation-induced emission, HPLC of Formula: 219537-97-0, the publication is Dyes and Pigments (2017), 118-128, database is CAplus.

A series of new diarylethene compounds with both photochromism and aggregation-induced emission have been synthesized by connecting tetraphenylethene and triphenylethene to the bisthienylethene. All the four compounds exhibit good photochromism upon irradiation with alternative UV and visible light. And they are all provided with aggregation-induced emission properties in THF solution with different fraction of water, non-emissive in the pure THF solution but yellowish green fluorescence in the aggregate or solid state. Furthermore, the compounds connecting tetraphenylethene to the bisthienylethene were found to exhibit the stronger fluorescence emission in the aggregate or solid state than the ones connecting triphenylethene to the bisthienylethene.

Yang, Yi published the artcileNickel-Catalyzed Reductive Coupling for Transforming Unactivated Aryl Electrophiles into β-Fluoroethylarenes, Application In Synthesis of 637-07-0, the publication is Chemistry – An Asian Journal (2020), 15(1), 156-162, database is CAplus and MEDLINE.

We report herein a facile synthetic method for converting unactivated (hetero)aryl electrophiles into β-fluoroethylated (hetero)arenes via nickel-catalyzed reductive cross-couplings. This coupling reaction features the involvement of FCH₂CH₂ radical intermediate rather than β-fluoroethyl manganese species which provides effective solutions to the problematic β-fluoride side eliminations. The practical value of this protocol is further demonstrated by the late-stage modification of several complex ArCl or ArOH-derived bioactive mols.

We report a series of compounds 1-17 derived from the antiepileptic drug Sulthiame (SLT) from which both the benzenesulfonamide and the sultam moiety were retained. All compounds were tested in vitro for their inhibition activity against the human (h) Carbonic Anhydrase (CA; EC 4.2.1.1) I, II, VII, IX and XII isoforms. Among the series, derivatives 1 and 11 showed great enhancement of both inhibition potency and selectivity towards the hCA VII isoform, when compared to the reference SLT drug. The binding mode of 11 within the hCA VII active site was deciphered by means of X-ray crystallog. and revealed the sultam moiety being exposed to the rim of the active site. In vivo experiments on a model of neuropathic pain induced by oxaliplatin clearly showed 11 being an effective pain relieving agent and therefore worth of further exploitation towards the validation of the hCA VII as new target for the management of neuropathies.
