Copper-Catalyzed Aminoarylation of Alkenes via Aminyl Radical Addition and Aryl Migration

We describe a new strategy for aminoarylation of alkenes by copper-catalyzed smiles rearrangement using O-benzoylhydroxylamines as the amine reagent. This method affords various β-amino amide derivatives possessing a quaternary carbon center with wide functional group tolerance and high regioselectivity. The mechanistic studies indicate that the transformation can involve aminyl radical intermediates under acid-free condition.

Acid-Promoted Expeditious Syntheses of Aminated Dibenzosultams via Palladium/Norbornene Cooperatively Catalysed C?H Amination/Arylation

Herein we reported a protocol to access aminated benzofused sultams through sequential ortho-amination, followed by ipso-arylation of aryl iodide bearing sulfonamide functional group via palladium/norbornene coorperative catalysis. This reaction has showcased a broad spectrum of substrate scope under mild conditions with moderate to good efficiency. (Figure presented.).

External-oxidant-free amino-benzoyloxylation of unactivated alkenes of unsaturated ketoximes with: O -benzoylhydroxylamines

A new copper-catalyzed two-component amino-benzoyloxylation of unactivated alkenes of unsaturated ketoximes with O-benzoylhydroxylamines as the benzoyloxy sources is developed. Chemoselectivity of this method toward amino-benzoyloxylation or oxy-benzoyloxylation of alkenyl ketoximes relies on the position of the tethered olefins, and provides an external-oxidant-free alkene difunctionalization route that directly utilizes O-benzoylhydroxylamines as the benzoyloxy radical precursors and internal oxidants for the divergent synthesis of cyclic nitrones and isoxazolines.

Palladium-Catalyzed C-H Amination/[2 + 3] or [2 + 4] Cyclization via C(sp3or sp2)-H Activation

This report describes a palladium-catalyzed Catellani reaction consisting of amination/[2 + 3] or [2 + 4] cyclization via a carboxylate ligand-exchange strategy. This method effectively activates ortho-substituents that avoid a second C-H palladation. The scope of substrates was broad, o-methyl-substituted iodoarenes were applied to the reaction smoothly, and o-phenyl-substituted iodoarenes can also be obtained by this method. In terms of mechanism, density functional theory calculations proved the sequence of the key five-membered aryl-norbornene-palladacycle intermediate formation and C(sp3 or sp2)-H activation.

An unprecedented cobalt-catalyzed selective aroylation of primary amines with aroyl peroxides

A novel and facile cobalt-catalyzed selective aroylation of primary amines with aroyl peroxides was developed for the synthesis of aryl amides. It was unprecedented that C[sbnd]N bond formation product was selectively generated without the common N[sbnd]O bond formation product. Aroyl peroxides act as the sole aroylation reagent without additional base or oxidant. The reactions proceeded under mild conditions and showed broad substrates scope with a series of primary amines and aroyl peroxides.

A carboxylate-assisted amination/unactivated C(sp2)-H arylation reactionviaa palladium/norbornene cooperative catalysis

This report describes a carboxylate-assisted palladium-catalysed Catellani reaction, which is compatible withortho-amination and unactivated C(sp2)-H arylation. This method was used to synthesize a series of 1-amino substituted dihydrophenanthridines, phenanthridines and 6H-benzo[c]chromenes. Based on kinetic isotope experiments, the kinetic curve proves that pivalic acid accelerates the reaction rate of unactivated C(sp2)-H activation, and thus this rate can keep up with the five membered aryl-norbornene-palladacycle (ANP) intermediate.

Palladium-Catalyzed Amination/Dearomatization Reaction of Indoles and Benzofurans

This report describes a palladium-catalyzed dearomatization and amination tandem reaction of 2,3-disubstituted indoles and benzofurans via the Catellani strategy. This reaction provides a new method for the construction of amino-substituted indoline-fused cyclic and benzofuran spiro compounds in good yields. The reaction has broad functional group compatibility and substrate scope.

DMAP and PivOH-promoted amination/allenization reaction

This report described the first DMAP and PivOH-promoted ortho-C-H amination and ipso-allenization reaction of iodobenzenes realized by Pd/norbornene cooperative catalysis. Based on control experiments and DFT calculations, we speculated that the three ligands have different functions and mechanism paths in the reaction. This journal is

Synthesis of C4-Substituted Indoles via a Catellani and C-N Bond Activation Strategy

This paper describes the case of a cross study between the C-N bond cleavage reaction field and the Catellani-Lautens reaction system. A series of highly functionalized C4-substituted indoles were synthesized using this strategy. By screening the alkyl groups of amines, the energy barrier of C-N bond cleavage reaction was reduced and the corresponding allenization products were avoided. Finally, the density functional theory calculation shows that the inert C-N bond activation reaction is not a concerted process; on the contrary, the coupling reaction first generates indole quaternary ammonium salt, and then C-N bond cleavage occurs via an SN2 process.

Palladium-Catalyzed Chemoselective Synthesis of 2-Aminocinnamyl Esters via Sequential Amination and Olefination of Aryl Iodides

We report a highly chemoselective palladium-catalyzed Catellani-type amination of aryl iodides terminated by the Heck reaction using allylic esters as terminating reagents. 2-Aminocinnamyl esters were formed exclusively via β-H elimination rather than β-OAc elimination without the assistance of a silver salt. This protocol represents a useful extension of Catellani-type transformations.
