Harnessing hypervalent iodonium ylides as carbene precursors: C-H activation of: N -methoxybenzamides with a Rh(iii)-catalyst

Hypervalent iodonium ylides expeditiously generate carbenes which undergo domino intermolecular C-H activation followed by intramolecular condensation in the presence of N-methoxybenzamide as a starting material and a Rh(iii)-catalyst to afford dihydrophenanthridines. KIE studies and DFT calculations were performed to substantiate the mechanistic pathway. To extend the synthetic utilisation, fluorescent pyranoisocoumarins were achieved by using Rh(iii)-catalyzed peri-C-H/O-H activation/annulation reactions.

Palladium-Catalyzed Inert C?H Bond Activation and Cyclocarbonylation of Isoquinolones with Carbon Dioxide Leading to Isoindolo[2,1-b]isoquinoline-5,7-Diones

A palladium-catalyzed inert C?H bond activation and cyclocarbonylation of isoquinolones leading to isoindolo[2,1-b]isoquinoline-5,7-diones under 1 atm of carbon dioxide has been developed. This transformation features high regio- and chemo-selectivity, step-economy, and good functional group tolerance. Most of the corresponding products were obtained in moderate to good yields. It offers an alternative approach for the synthesis of useful diverse isoindolo[2,1-b]isoquinoline-5,7-dione derivatives. (Figure presented.).

Rhodium(III)-catalyzed chemodivergent annulations between: N-methoxybenzamides and sulfoxonium ylides via C-H activation

Chemodivergent and redox-neutral annulations between N-methoxybenzamides and sulfoxonium ylides have been realized via Rh(iii)-catalyzed C-H activation. The sulfoxonium ylide acts as a carbene precursor, and coupling occurs under acid-controlled condition

Selective mono-alkylation of N-methoxybenzamides

We report our latest discovery of norbornene derivative modulated highly mono-selective ortho-C-H activation alkylation reactions on arenes bearing simple mono-dentate coordinating groups. The reaction features the use of readily available benzamides and alkyl halides. During the study, we prepared 30 mono-alkylated aryl amides in good yields with good mono-selectivity. We have also demonstrated that structurally rigid alkenes such as norbornene and its derivatives are a good class of ligand and could be used for future direct C-H functionalizations. The utilization of norbornene type ligands for assistance in C-H activation processes has opened a new window for future molecular design using direct C-H functionalization strategies.

Solvent-Controlled, Tunable β-OAc and β-H Elimination in Rh(III)-Catalyzed Allyl Acetate and Aryl Amide Coupling via C-H Activation

The Heck reaction between arenes and allyl acetate has led to cinnamyl derivatives and allyl products depending on the regioselectivity of β-elimination. The regioselectivity can be controlled by the solvent in the Rh(III)-catalyzed arene-allyl acetate coupling via C-H activation: (1) in THF, cinnamyl derivatives via β-H elimination were generated; (2) in MeOH, allyl products via β-OAc elimination were produced. Both routes have advantages such as excellent γ-selectivity toward allyl acetate, good to excellent yields, and broad substrate scope.

Rh-Catalyzed annulations of: N -methoxybenzamides with ketenimines: Synthesis of 3-aminoisoindolinones and 3-diarylmethyleneisoindolinones with strong aggregation induced emission properties

Rhodium-catalyzed C-H activation/annulation reactions of ketenimines with N-methoxybenzamides furnished 3-aminoisoindolin-1-ones and 3-(diarylmethylene)isoindolin-1-ones. The synthesized 3-(diarylmethylene)isoindolin-1-ones exhibited aggregation induced emissions in aqueous tetrahydrofuran solution and strong green-yellow emissions in solids.

Palladium-Catalyzed Deaminative Phenanthridinone Synthesis from Aniline via C-H Bond Activation

This work reports palladium-catalyzed phenanthridinone synthesis using the coupling of aniline and amide by formation of C-C and C-N bonds in a one-pot fashion via dual C-H bond activation. It involves simultaneous cleavage of four bonds and the formation of two new bonds. The present protocol is ligand-free, takes place under mild reaction conditions, and is environmentally benign as nitrogen gas and water are the only side products. This transformation demonstrates a broad range of aniline and amide substrates with different functional groups and has been scaled up to gram level.

Ir(III)-Catalyzed Carbenoid Functionalization of Benzamides: Synthesis of N-Methoxyisoquinolinediones and N-Methoxyisoquinolinones

A mild and efficient Ir(III)-catalyzed C-H carbenoid functionalization strategy has been developed to access N-methoxyisoquinolinediones and N-methoxyisoquinolinones. The reaction proceeds efficiently in high yield at room temperature over a broad range of substrates without requirement of any additional oxidants or a base.

Rhodium(iii)-catalyzed C-H/C-C activation sequence: Vinylcyclopropanes as versatile synthons in direct C-H allylation reactions

Succession of C-H activation and C-C activation was achieved by using a single rhodium(iii) catalyst. Vinylcyclopropanes were used as versatile coupling partners. Mechanistic studies suggest that the olefin insertion step is rate-determining and a facile β-carbon elimination is involved, which represents a novel ring opening mode of vinylcyclopropanes.

Amides and Ethers as Chemoselective Surrogates for Copper(II)-Catalyzed ortho Benzoyloxylation of 2-Phenylpyridines

Chemoselective ortho benzoyloxylation of 2-phenylpyridine derivatives using amides and ethers as novel arylcarboxy sources using a Cu(II)/TBHP catalytic system has been reported. It is a simple protocol for ortho benzoyloxylation using amides and ethers as surrogates. A broad range of amides and ethers was found to be compatible under optimized reaction conditions to provide the corresponding products in good to excellent yield. The reaction proceeds through the cleavage of C-N, C-O, and C-H bonds and the formation of a new C-O bond via C-H functionalization.
