The iron-catalyzed intermolecular aziridination of alkenes with hydroxylamine derivatives is described. Using simple iron(II) sources and readily available ligands, the formal (2 + 1) cycloaddition process proved to be efficient on both styrenes and

Conventional approaches on using hydroxylamine derivatives as single nitrogen sources, for the construction of n-membered (n > 3) N-heterocycles, rely upon two chemical operations by involving sequ...

A recent work published in Science by Cramer and co-workers demonstrates chiral cyclometalated Ir(III) complexes can selectively catalyze the hydrogenation of carbon-nitrogen double bond of oximes with the aid of acid. Various oximes can be hydrogena

N-Pyridyl hydroxylamine derivatives were prepared via copper-catalyzed cross-coupling of orthogonally functionalized hydroxylamines with iodopyridines. Various amino- and hydroxyl-protecting groups were tolerated. A total of 20 examples were synthesi

Functionalized imidazolidin-2-one were prepared by using an iron-catalyzed alkene oxyamination reaction. Hydroxylamine derivatives were used in this atom-economical process, and the addition of an external oxidant was not required. The conditions dev

A novel avenue of C–O bond construction was facilely achieved via Selectfluor-induced oxygenation of C(sp2)–H bonds of N-substituted anilines by reacting with N-hydroxyphthalimide or N-hydroxymaleimide without any metal catalyst. A variety of N-a

Oxygen-substituted isocyanates (O-isocyanates) are rare isocyanates with a reported propensity to trimerize, a side-reaction that severely limited their use in synthesis. Herein, the development of blocked (masked) O-isocyanate precursors that form t

The additions of lithiated alkoxyallenes to electrophiles, such as carbonyl compounds, thioketones, imines, and nitrones, provide the expected primary addition products. These alkoxyallene intermediates undergo ring-closure reactions under quite diff

A conceptually new and synthetically valuable radical Smiles rearrangement reaction is reported under undivided electrolytic conditions. This protocol employs an entirely new strategy for the electrochemical radical Smiles rearrangement. Remarkably,
