Ruthenium(II)-catalyzed deoxygenation of ketones was written by Gui, Ruohua;Li, Chao-Jun. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2022.Name: 4,4′-Methylenediphenol The following contents are mentioned in the article:

The classical Wolff-Kishner reduction plays a key role in organic synthesis to convert carbonyl functionalities into methylene groups; however, it generally requires harsh reaction conditions and a strategy with wider applications demands further development. Herein, a ruthenium-catalyzed Wolff-Kishner type reduction of ketones is developed with 31 examples under mild conditions. This strategy tolerates aryl and alkyl ketones with reactive functional groups including halogens, hydroxyls, carboxylic acid, unsaturated functional groups, and so on. The corresponding methylene products were obtained in 32% to 95% yields while using water or methanol as solvents. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Name: 4,4′-Methylenediphenol).

4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Name: 4,4′-Methylenediphenol

One-step purification of tag free and soluble lamin B1 from an E. coli bacterial expression system was written by Raman, Rajeev;Karpova, Anna;Kreutz, Michael R.. And the article was included in Protein Expression and Purification in 2022.Name: (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol The following contents are mentioned in the article:

Lamin B1 is an intermediate filament protein that is a core component of the nuclear lamina. Structural studies and biochem. characterization of lamin B1 are severely hampered by the tendency of the protein to form inclusion bodies in E. coli bacterial expression systems. Therefore, the purity and consistency of the protein varies from batch to batch. In this work, we have purified a tag-free lamin B1 protein from a soluble fraction following bacterial expression. We also checked the functional properties of the purified as well as of the subsequently lyophilised protein. The current protocol helps to purify functional lamin B1 in a single step. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Name: (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol).

3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Application In Synthesis of 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride

Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Product Details of 65-22-5
