The transition-metal-catalyzed nitrenoid transfer reaction is one of the most attractive methods for installing a new C-N bond into diverse reactive units. While numerous selective aminations are known, understanding complex structural effects of the

Catalytic carbon-nitrogen bond formation in hydrocarbons is an appealing synthetic tool to access valuable nitrogen-containing compounds. Although a number of synthetic approaches have been developed to construct a bifunctional α-amino carbonyl scaf

Described herein is the Ir-catalyzed enantioselective access to chiral spirolactam products via the nitrenoid transfer to aromatic ipso-carbons. The key strategy for precise stereocontrol is to enhance the secondary attractive and repulsive interacti

Two mechanistic pathways, that is, electrocyclization and electrophilic aromatic substitution, are operative in most intramolecular C-H amination reactions proceeding by metal nitrenoid catalysis. Reported here is an alternative mechanistic scaffold

Described herein is a mechanism-based approach to develop a versatile C-H amidation protocol under IrIII catalysis. Reaction kinetics of a key C-N coupling step with acyl azide and 1,4,2-dioxazol-5-one led us to conclude that dioxazolones are much mo

Guiding nitrenes away from a migration Nitrogen conventionally shares its electrons in three bonds with one or more partners. A singly bonded nitrogen, or nitrene, is exceptionally reactive and can insert itself into normally inert C–H bonds. If th
