(Figure Presented) Boron can do it! Readily prepared catecholboron enolates act as regulators in the controlled radical polymerization of alkyl and aryl vinyl ketones. Control is achieved by an unprecedented reversible radical boron group transfer (BGT) between enoyl radicals (see scheme). Polymers with M n-1 and a polydispersity index of 1.3 can be obtained by this process.

Paragraph 0063-0064, (2021/09/14)
The present invention relates to novel compounds exhibiting anti-inflammatory activity. The compound of the present invention plays a critical role in the production of inflammatory prodrug (pro-inflammatory cytokines) and has an excellent inhibitory effect on p38 MAPK, which is known to cause inflammatory diseases, and thus can be used as a therapeutic agent for inflammatory diseases.

A straightforward synthesis of acylating reagents such as Weinreb and MAP amides from aromatic, aliphatic carboxylic acids, and amino acids using PPh3/NBS combination is described. A chemo-selective modification of the carboxylic acid group into Weinreb amide in the presence of more reactive aldehydes and ketones is presented. All reactions were performed at ambient temperature under air using undried commercial grade solvent. Furthermore, the present methodology could be performed at a gram scale under inert-free reaction conditions. In addition, 7-azaindoline amide auxiliary (used for catalytic asymmetric aldol- and Mannich-type reactions), which behaves like Weinreb amide is also synthesized under similar reaction conditions.
