Absolute Reliability

The sulfur(VI) fluoride exchange reaction (SuFEx), developed by Sharpless and co-workers in 2014, is a new category of click reaction that creates molecular connections with absolute reliability and unprecedented efficiency through a sulfur(VI) hub. Ethenesulfonyl fluoride (ESF), as one of the most important sulfur(VI) hubs, exhibits extraordinary reactivity in SuFEx click chemistry and organic synthesis. This review summarizes the chemical properties and applications of ESF in click chemistry, organic chemistry, materials science, medicinal chemistry and in many other fields related to organic synthesis.1 Introduction2 Chemical Transformations of ESF3 Chemical Transformations of 2-Arylethenesulfonyl Fluorides4 Novel SuFEx Reagents Derived from ESF5 Applications of ESF Derivatives in Medicinal Chemistry6 Applications of ESF Derivatives in Materials Science7 Conclusion

Unsaturated Carboxylic Acids

The oxidative cyclization of β-substituted β,γ-unsaturated carboxylic acids using a hypervalent iodine reagent to provide 4-substituted furan-2-one products, is reported. In this cyclization, the use of a highly electrophilic PhI(OTf)2, which is in situ prepared from PhI(OAc)2 and Me3SiOTf, is crucial. Depending on the substitution pattern at the α-position of the substrates, furan-2(5H)-ones or furan-2(3H)-ones are produced. Thus, the present method offers a useful tool for accessing various types of 4-substituted furan-2-ones that are important structural motifs in the field of organic chemistry and medicinal chemistry.

Synthetic Intermediates

Organoboron compounds continue contributing substantially to advances in organic chemistry with their increasing role as both synthetic intermediates and target compounds for medicinal chemistry. Particularly attractive methods of their synthesis are based on the direct borylation of C−H bonds of available starting materials since no additional pre-functionalization steps are required. However, due to the high abundance of C−H bonds with similar reactivity in organic molecules, synthetically useful C−H borylation protocols demand sophisticated strategies to achieve high regio- and stereoselectivity. For this purpose, selective transition-metal-based catalysts have been developed, with group 9-centered catalysts being among the most commonly utilized. Recently, a multitude of diverse strategies has been developed to push the boundaries of C−H borylation reactions with respect to their regio- and enantioselectivity. Herein, we provide an overview of approaches for the C−H borylation of arenes, alkenes, and alkanes based on group 9-centered catalysts with a focus on the recent literature. Lastly, an outlook is given to assess the future potential of the field.
