copper‐catalyzed cross‐coupling of 1,2‐dihaloalkenes and amides leads to cyclic β‐haloenamides, which can participate in a second cross‐coupling reaction to efficiently synthesize highly functionalized cyclic enamides. The selectivity of the intramolecular coupling between exo‐ and endocyclic regioisomers is a crucial synthetic factor and can be influenced by the structure of the substrate and the reaction conditions

Selective methods for introducing protein post-translational modifications (PTMs) within living cells have proven valuable for interrogating their biological function. In contrast to enzymatic methods, abiotic catalysis should offer access to diverse and new-to-nature PTMs. Herein, we report the boronate-assisted hydroxamic acid (BAHA) catalyst system, which comprises a protein ligand, a hydroxamic

The cyclisation of alkynyl amido- and amino-malonates in the presence of manganese(III) acetate gives exo-alkylidene pyrrolidinones and pyrrolidines with a preference for the (Z)-alkene product isomer.
