C(sp³)-H Monoarylation of methanol enabled by a bidentate auxiliary was written by Gou, Quan;Yuan, Binfang;Ran, Man;Ren, Jian;Zhang, Ming-zhong;Tan, Xiaoping;Yuan, Tengrui;Zhang, Xing. And the article was included in Organic Letters in 2021.COA of Formula: C16H22O11 The following contents are mentioned in the article:

With the assistance of a practical directing group (COAQ), the first catalytic protocol for the palladium-catalyzed C(sp³)-H monoarylation of methanol has been developed, offering an invaluable synthesis means to establish extensive derivatives of crucial arylmethanol functional fragments. Furthermore, the gram-scale reaction, broad substrate scope, excellent functional group compatibility, and even the practical synthesis of medicines further demonstrate the usefulness of this strategy. This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3COA of Formula: C16H22O11).

(2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Topological modeling of analgesia was written by Mathur, K. C.;Gupta, Sunita;Khadikar, P. V.. And the article was included in Bioorganic & Medicinal Chemistry in 2003.Name: 4-Acetamidophenyl 2-acetoxybenzoate The following contents are mentioned in the article:

Analgesic activity (log IC) of a large series of 97 analgesics was modeled topol. using a series of distance-based topol. indexes. The results show that analgesic activity (log IC) exhibit inter familial correlation and these can only be modeled by splitting 97 analgesics into five different categories. The regression analyses of the data show that the Wiener (W)-, branching (B)- and first-order connectivity (χ)- indexes are the better topol. indexes for modeling the activity (log IC), and that the W index gave excellent results. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5Name: 4-Acetamidophenyl 2-acetoxybenzoate).

4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Name: 4-Acetamidophenyl 2-acetoxybenzoate

Selective actions of aspirin- and sulfasalazine-like drugs against prostaglandin synthesis and breakdown was written by Moore, P. K.;Hoult, J. R. S.. And the article was included in Biochemical Pharmacology in 1982.Reference of 5003-48-5 The following contents are mentioned in the article:

Groups of 10 aspirin- and 5 sulfasalazine-like drugs were tested as inhibitors of prostaglandin synthesis and breakdown. The aspirin-like drugs exhibited selectivity against formation but also inhibited breakdown at higher doses. The sulfasalazine-like drugs exhibited selectivity against breakdown and some, but not all, inhibited formation at higher doses. It is proposed that there are 2 pharmacol. distinct groups of drugs, and that they can be characterized by the ratios of ID₅₀ values against breakdown and formation. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5Reference of 5003-48-5).

4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Reference of 5003-48-5

A new family of chiral C₂ sym. tetraazamacrocycles, coined ISAC for IminoSugar Aza-Crown, incorporating two iminosugars adopting a ⁴C₁ conformation is disclosed. Multinuclear NMR experiments on the corresponding Cd²⁺ complex show that the ISAC is a strong chelator in water and its tetramine cavity adopts a conformation similar to that of the parent Cd-cyclam complex. Similar behavior is observed with Cu²⁺ in solution, with enhanced stability compared to the Cu-cyclam complex.

Discrimination and selection of new potential antibacterial compounds using simple topological descriptors was written by Murcia-Soler, Miguel;Perez-Gimenez, Facundo;Garcia-March, Francisco J.;Salabert-Salvador, M. Teresa;Diaz-Villanueva, Wladimiro;Medina-Casamayor, Piedad. And the article was included in Journal of Molecular Graphics & Modelling in 2003.SDS of cas: 5003-48-5 The following contents are mentioned in the article:

The aim of the work was to discriminate between antibacterial and non-antibacterial drugs by topol. methods and to select new potential antibacterial agents from among new structures. The method used for antibacterial activity selection was a linear discriminant anal. (LDA). It is possible to obtain a QSAR interpretation of the information contained in the discriminant function. We make use of the pharmacol. distribution diagrams (PDDs) as a visualizing technique for the identification and selection of new antibacterial agents. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5SDS of cas: 5003-48-5).

4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.SDS of cas: 5003-48-5

And the article was included in Chemistry Letters in 2019.Application of 604-69-3 The following contents are mentioned in the article:

Tetraethylene glycol (TEG)-conjugated (C₆₀-I_h)[5,6]fullerene (TEG-C₆₀) was synthesized as a soluble mol. building block generating C₆₀-based conjugates with advanced properties. The improved solubility allowed the glycosylation reaction with TEG-C₆₀ using a Lewis acid in chloroform at low temperature The resultant glycoconjugated TEG-C₆₀ was characterized in terms of water solubility, ability to generate reactive oxygen species (ROS), and photodynamic activity. This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3Application of 604-69-3).

(2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Application of 604-69-3
