Abstract Developing skeletal editing tools is not a trivial task, and realizing the corresponding single-atom transmutation in ring system without altering size even more challenging. Here, we introduce strategy that enables polycyclic arenols, highly prevalent motif bioactive molecules, to be readily converted into N -heteroarenes through carbon–nitrogen transmutation. The reaction features selective nitrogen insertion C–C bond of arenol frameworks by azidative dearomatization aryl migration, followed ring-opening, ring-closing (ANRORC) achieve carbon-to-nitrogen aromatic framework arenol. Using widely available arenols as -heteroarene precursors, this alternative approach allows streamlined assembly complex heteroaromatics with broad functional group tolerance. Finally, pertinent transformations products, including synthesis biheteroarene skeletons, were conducted exhibited significant potential materials chemistry.

Acyl hydrazides are widely found in bioactive compounds and have important applications as versatile synthetic intermediates. In the current report, a photoredox-catalyzed hydroacylation of azobenzenes was disclosed with carboxylic acids acylation reagent, affording variety N,N′-disubstituted hydrazides. The process possesses advantages mild reaction conditions, broad substrate scope, high efficiency. Preliminary mechanistic investigation indicated that addition an acyl radical to azo compound should be involved.

Cross-coupling azide and isocyanide have recently gained recognition as ideal methods for efficiently synthesizing asymmetric carbodiimides. This reaction exhibits high rates, efficiency, favorable atom/step/redox economy. It enables the nitrene-transfer process, facilitating formation of C-N bonds providing a direct cost-effective synthetic strategy generating diverse These carbodiimides are highly reactive compounds that can undergo

In this work, a tunable reaction of metal acyl nitrene with ylides is reported for the divergent synthesis enamides and α,α-dicarbonyl phosphorus ylides. The featured mild conditions, good efficiency, broad generality. particular, resulting could be structurally elaborated into potential useful scaffolds. Mechanism investigation suggests that formation was ascribed to nucleophilic substitution ferric sulfur It believed represents an initial example preparing from iron-catalyzed transfer.

Here, we present the first examples of amino-trifluoroacetoxylations alkenes using N-alkoxy carbamate tethers. The trifluoroacetate group can be conveniently removed from product by treatment with a solution NH3 in MeOH. Hypervalent iodine oxidants mediate this transformation, providing “green” alternative to existing intramolecular aminohydroxylation protocols which use toxic metals such as osmium. In all cases examined, reaction is regioselective and stereospecific, geometry starting alkene controlling diastereomeric outcome. By analogy prior art our own observations, posit that transient nitrenium species serves key intermediate transformation.
