  • Bridged bicyclic frameworks are valuable in medicinal chemistry but difficult to access from simple saturated precursors. In situ generation of cyclic 1,3-dienes from unactivated carboxylic acids remains challenging. Now it has been shown that ligand-guided Pd(II) C–H activation enables multi-step diene formation for highly selective formal Diels–Alder reactions.

  • Diverse methyl β-C−H functionalizations of ketones and esters are enabled by cationic Pd(II) complexes with MPANA ligands, offering access to spirocyclic and fused ring systems through enhanced catalyst–substrate affinity.

  • Enantioselective catalytic C(sp3)–H fluorination has been limited to electrophilic fluorine sources. Now chiral palladium catalysts bearing amino sulfonamide ligands enable enantioselective incorporation of nucleophilic fluoride into unactivated aliphatic C–H bonds with demonstrated applications to 18F-radiolabelling using [18F]KF.
