Zhu, Haiqian; Zheng, Hanliang; Zhang, Junhua; Feng, Jian; Kong, Lichun; Zhang, Fang; Xue, Xiao-Song; Zhu, Gangguo published their research in Chemical Science in 2021. The article was titled 《Solvent-controlled photocatalytic divergent cyclization of alkynyl aldehydes: access to cyclopentenones and dihydropyranols》.Application of 16629-19-9 The article contains the following contents:

Divergent synthesis is a powerful strategy for the fast assembly of different mol. scaffolds from identical starting materials. Herein, a solvent-controlled photocatalytic divergent cyclization of alkynyl aldehydes with sulfonyl chlorides for the direct construction of highly functionalized cyclopentenones and dihydropyranols that widely exist in bioactive mols. and natural products has been described. D. functional theory calculations suggest that a unique N,N-dimethylacetamide-assisted 1,2-hydrogen transfer of alkoxy radicals is responsible for the cyclopentenone formation, whereas a C-C cleavage accounts for the selective production of dihydropyranols in acetonitrile and water at 50°C. Given the simple and mild reaction conditions, excellent functional group compatibility, forming up to four chem. bonds, and tunable selectivity, it may find wide applications in synthetic chem. In the experiment, the researchers used Thiophene-2-sulfonyl chloride(cas: 16629-19-9Application of 16629-19-9)

Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides.

Using the ring-opening metathesis polymerization, a new amphipathic triblock polynorbornene-based copolymer containing reactive aldehyde, redox-active ferrocene, and dendritic oligoethylene glycols units (PNCHO-PNFc-PNTEG), was controllably synthesized and exhibited the dual-cargo loading capacity with the oxidation/pH stimuli-responsive behavior. PNCHO-PNFc-PNTEG could conjugate the amino-containing doxorubicin (DOX) by the acid-sensitive Schiff base reaction. The DOX-grafted PNCHO-PNFc-PNTEG could further self-assemble into spherical nanoscale polymeric micelles that can encapsulate the second model cargo rhodamine B (RhB). The step-by-step release behavior of the loaded two cargos was observed Namely, the loaded RhB could be firstly released under the stimulus of oxidant, and the grafted DOX could be then released under acidic condition. Moreover, PNCHO-PNFc-PNTEG micelles showed excellent biocompatibility both in in vitro L929 cell test and in vivo zebrafish embryo toxicity experiments Thus, PNCHO-PNFc-PNTEG as polymeric carrier has great application potential in the medical field for controllable drug release.

In 2022,Kim, Thomas T.; Lee, Chungwoo; Kim, Dongwook; Lee, Hee-Seung; Han, Sunkyu published an article in Organic Letters. The title of the article was 《Synthesis and Reactivity of 1-Hydroxyherquline A》.Application of 5781-53-3 The author mentioned the following in the article:

Herein, we present the synthesis of 1-hydroxyherquline A and describe its reactivity discovered during its attempted conversion to herquline A, a long-sought natural product target in the synthetic chem. community. The strategic installation of the C1 hydroxyl group enabled the key aza-Michael addition-mediated N10-C2 bond formation and eventually access to 1-hydroxyherquline A, the most advanced herquline A congener reported to date. Our attempted reductive transformation of 1-hydroxyherquline A to herquline A was challenged by the extremely strained bowl-shaped pentacyclic structures of key precursors that prevented either radical formation at C1 or protonation (or hydrogenation) from the desired face. These discoveries regarding the innate chem. reactivities of advanced intermediates toward herquline A may prove useful in efforts toward this formidable target. After reading the article, we found that the author used Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3Application of 5781-53-3)

Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3) belongs to acyl chlorides. In the laboratory, acyl chlorides are generally prepared by treating carboxylic acids with thionyl chloride (SOCl2). The reaction is catalyzed by dimethylformamide and other additives.Application of 5781-53-3

Computed Properties of ClNaIn 2020 ,《The application of pulsed electric field as a sodium reducing strategy for meat products》 appeared in Food Chemistry. The author of the article were Bhat, Zuhaib F.; Morton, James D.; Mason, Susan L.; Bekhit, Alaa El-Din A.. The article conveys some information:

This study investigated the potential of pulsed elec. field (PEF) as a sodium-reduction strategy for processed meat. Beef jerky was used as a model and prepared using different levels of NaCl, viz. 2.0% (control), 1.2% (T1) and 1.2% along with PEF processing (T2). A significant (p < 0.05) effect of PEF was observed on shear force (N) and toughness (N/mm s) of the products, which was also reflected in sensory scores. No effects for PEF were observed on color, yield (%) and oxidative and microbial stability. PEF-treated samples (T2) had significantly (p < 0.05) lower sodium content than the control, however, the sensory scores were comparable (p > 0.05) with control and >84% of the panellists preferred T2 samples over T1 for saltiness. Results suggest that PEF treatment improved saltiness by influencing the salt diffusion and sodium delivery that led to better perception during chewing. PEF could be a novel method to produce healthier reduced-sodium meat products. In the experiment, the researchers used many compounds, for example, Sodium chloride(cas: 7647-14-5Computed Properties of ClNa)

《Changes in protein properties and tissue histology of tuna meat as affected by salting and subsequent freezing》 was written by Jiang, Qingqing; Jia, Ru; Nakazawa, Naho; Hu, Yaqin; Osako, Kazufumi; Okazaki, Emiko. Computed Properties of ClNaThis research focused ontuna fish meat salting freezing water holding histol; Freezing; Ice crystal morphology; Physicochemical properties; Salting; Tissue histology; Tuna; Water-holding capacity. The article conveys some information:

The effects of salting and subsequent freezing on the physicochem. and histol. properties of frozen-thawed tuna (Thunnus obesus) meat were investigated. Salting facilitated the microstructural recovery as indicated by the decrease or disappearance of intracellular holes. The yield of the 0.5 M and 1 M salted samples increased by 20% which was evaluated by the mass ratio of products to raw material. Morphol. transformation from ice columns to spherical or ellipsoidal ice crystals was tentatively attributed to the extraction/solubilization of myofibrillar proteins, contributing to increased water-holding capacity. However, increased thawing loss and centrifuging loss after thawing were observed in the 2 M and 3 M salted samples with large ice crystals and enlarged extracellular spaces. These modifications were closely associated with the changes in protein properties. In conclusion, enhanced water-holding capacity, high yield, and good freezing stability can be achieved by optimal salting. The experimental process involved the reaction of Sodium chloride(cas: 7647-14-5Computed Properties of ClNa)
