Asymmetric catalysis

Unnatural α-amino acid synthesis

Direct, stereocontrolled functionalization of ubiquitous C(sp3)–H bonds represents the most efficient route towards highly valuable molecules from feedstock chemicals. Now, diverse, enantioenriched, unnatural α-amino acids are obtained from readily available carboxylic acids in one step via iron-catalysed asymmetric nitrene transfer, overcoming the reactivity and selectivity challenges of intermolecular C–H amination.
