The esters of 1,2-azido alcohols were transformed into [small alpha]-amido ketones without external oxidants through the Ru-catalyzed formation of N-H imines with liberation of N2 followed by intramolecular migration of the...

radical acylation of imines with α-ketoacids has been achieved, enabled by an electron-donor–acceptor (EDA) complex. This EDA complex-mediated process eradicates the use of a photocatalyst. Visiblelight is used as the sole promoter for this reaction, and CO2 is the only side product. Substrates with amide, cyanide, ester, ether, halides, and heterocycles were compatible. This radical acylation allows
Electrophilic amination of enolates with oxaziridines: effects of oxaziridine structure and reaction conditions

A range of N-alkoxycarbonyl- and N-carboxamido-oxaziridines has been prepared to test the effects of oxaziridine structure on yields of enolate amination product. Side-products arising from reaction of aldehyde-derived oxaziridines with base were identified, while a ketone-derived oxaziridine afforded moderate yields of amination product with stabilised carbanions.
Novel N → C acyl migration reaction of acyclic imides: A facile method for α-aminoketones and β-aminoalcohols

The acyclic imides derived from primary benzylic amines and amino acid esters easily undergo the novel N → C acyl migration reaction via a base-generated carbanion, yielding the corresponding α-aminoketones which are expedient precursors for β-aminoalcohols.
