Catalyst-controlled site-selective activation of β- and γ-methylene carbon-hydrogen (C–H) bonds of free carboxylic acids is a long-standing challenge. Here we show that, with a pair of palladium catalysts assembled with quinoline-pyridone ligands

Enolate alkylation and conjugate addition into an α,β-unsaturated system have served as longstanding strategic disconnections for the installation of α or β-substituents on carbonyl-containing compounds. At the onset of our efforts to develop C

Reactive intermediates frequently play significant roles in the biosynthesis of numerous classes of natural products although the direct observation of these biosynthetically relevant species is rare. We present here direct evidence for the existence

Acetylcholine and S-adenosylmethionine exemplify the tetraalkylammonium (R4N+) and trialkylsulfonium (R3S+) ions used by Nature. The corresponding trialkyloxonium ions (R3O+), however, do not play a central role in biology most likely due to their hy
