Engineering membrane‐bound alkane monooxygenase from Marinobacter sp. for increased activity in the selective ω‐hydroxylation of linear and branched aliphatic esters

Protein Science, Volume 35, Issue 4, April 2026.
Abstract The regio‐ and stereoselective hydroxylation of unactivated C(sp3)‐H bonds is an important reaction in organic synthesis. While bacterial alkane monooxygenase AlkB catalyzes the terminal hydroxylation of aliphatic esters with excellent regioselectivity, the molecular principles of substrate recognition and selectivity of this integral membrane

Electrochemical Three‐Component Synthesis of Vinyl Sulfonamides via Decarboxylative Sulfonylation of Cinnamic Acids

ChemSusChem, Volume 19, Issue 6, 27 March 2026.
An efficient, metal‐free electrochemical three‐component reaction of cinnamic acids, SO2, and amines to access (E)‐β‐styryl sulfonamides is reported. Utilizing graphite electrodes and SO2 stock solutions, this decarboxylative protocol proceeds under mild conditions with high regio‐ and stereoselectivity.

Anomeric Amides: Valuable Reagents in Synthetic Organic Chemistry

Angewandte Chemie, Volume 138, Issue 12, 16 March 2026.
Enabling late‐stage transformations and skeletal editing, anomeric amides have recently emerged as powerful synthetic tools. Due to their unique properties, anomeric amides have been employed in reactions ranging from amination to halogenation. This minireview provides an overview of recent progress in using anomeric amides across a variety of ...
