WebSep 22, 2014 · In this study, thioether crosslinking was investigated for a 46 aa albumin-binding domain (ABD) derived from streptococcal protein G. ABD binds with high affinity to human serum albumin (HSA) and has been proposed as a fusion partner to increase the in vivo half-lives of therapeutic proteins. In the study, five ABD variants with single or ...

WebKOH promotes an unusual deoxidative coupling reaction of β-sulfinyl esters with benzylic trimethylammonium salts to produce thioethers. Enantiomerically enriched quaternary ammonium salts provide benzyl thioethers with clean inversion of the configuration. Q. Zhang, H. Feng, F. Chen, Z. He, Q. Zeng, J. Org. Chem., 2024, 86, 7806-7812. WebFeb 28, 2024 · A thioether or sulfide is a compound that has the following general structural formula. R 1, R 2 = alkyl groups and/or aryl groups. eg: The sulfur atom in a thioether molecule is called the thioether or sulfide group.
WebThiols and sulfides are the "sulfur equivalent" of alcohols and ethers. You can replace the oxygen atom of an alcohol with a sulfur atom to make a thiol; similarly, you can replace … WebA thioether (similar to sulfide) is a functional group in organic chemistry that has the structure R 1-S-R 2 as shown on right.

A convenient procedure allows the synthesis of esters and thioesters from the corresponding carboxylic acid using TFFH as the coupling reagent. The preparation of N -acyl-dithiocarbamates from carboxylic acids and 1,3-thiazolidine-2-thione is also described.
WebA thioether is a molecule with the group R-S-R. The first atom in R is a carbon. Thioether take their name from ethers. They have a sulfur instead of an oxygen atom between the two R. Thioethers can have very bad smells like thiols. They can also be called sulfides.
