Ligand-Enabled Alkynylation of C(sp3 )-H Bonds with Palladium(II) Catalysts.

ABSTRACT: The palladium(II)-catalyzed ?- and ?-alkynylation of amide C(sp3 )-H bonds is enabled by pyridine-based ligands. This alkynylation reaction is compatible with substrates containing ?-tertiary or ?-quaternary carbon centers. The ?-methylene C(sp3 )-H bonds of various carbocyclic rings were also successfully alkynylated.

The palladium(II)-catalyzed β- and γ-alkynylation of amide C(sp3 )-H bonds is enabled by pyridine-based ligands. This alkynylation reaction is compatible with substrates containing α-tertiary or α-quaternary carbon centers. The β-methylene C(sp3 )-H bonds of various carbocyclic rings were also successfully alkynylated. ...[more]

Ligand-Enabled Pd(II)-Catalyzed Bromination and Iodination of C(sp3)-H Bonds.

Project description:We herein report the palladium(II)-catalyzed bromination and iodination of a variety of ?-hydrogen-containing carboxylic acid and amino acid-derived amides. These reactions are exclusively enabled by quinoline-type ligands. The halogenated products obtained in this reaction are highly versatile and rapidly undergo further diversification. Further, we report the first example of a free carboxylic acid-directed Pd(II)-catalyzed C(sp3)-H bromination, enabled by quinoline ligands.

Ligand-Promoted Borylation of C(sp(3))-H Bonds with Palladium(II) Catalysts.

Project description:A quinoline-based ligand effectively promotes the palladium-catalyzed borylation of C(sp(3))-H bonds. Primary ?-C(sp(3))-H bonds in carboxylic acid derivatives as well as secondary C(sp(3))-H bonds in a variety of carbocyclic rings, including cyclopropanes, cyclobutanes, cyclopentanes, cyclohexanes, and cycloheptanes, can thus be borylated. This directed borylation method complements existing iridium(I)- and rhodium(I)-catalyzed C-H borylation reactions in terms of scope and operational conditions.

Ligand-Enabled, Palladium-Catalyzed ?-C(sp3)-H Arylation of Weinreb Amides.

Project description:We report the development of Pd(II)-catalyzed C(sp3)-H arylation of Weinreb amides. This work demonstrates the first example of using Weinreb amide as a directing group for transition metal-catalyzed C(sp3)-H activation. Both the inductive effect and the potential bidentate coordination mode of the Weinreb amides pose a unique challenge for this reaction development. A pyridinesulfonic acid ligand is designed to accommodate the weak, neutral coordinating property of Weinreb amides via preserving the cationic character of Pd center through zwitterionic assembly of Pd/ligand complexes. DFT studies of the C-H cleavage step indicate that the superior reactivity of 3-pyridinesulfonic acid ligand compared to pyridine, Ac-Gly-OH, and ligandless conditions originates from the stabilization of overall substrate-bound Pd species.

Ligand-enabled cross-coupling of C(sp3)-H bonds with arylboron reagents via Pd(II)/Pd(0) catalysis.

Project description:There have been numerous developments in C-H activation reactions in the past decade. Attracted by the ability to functionalize molecules directly at ostensibly unreactive C-H bonds, chemists have discovered reaction conditions that enable reactions of C(sp(2))-H and C(sp(3))-H bonds with a variety of coupling partners. Despite these advances, the development of suitable ligands that enable catalytic C(sp(3))-H bond functionalization remains a significant challenge. Herein we report the discovery of a mono-N-protected amino acid ligand that enables Pd(II)-catalysed coupling of ?-C(sp(3))-H bonds in triflyl-protected amines with arylboron reagents. Remarkably, no background reaction was observed in the absence of ligand. A variety of amine substrates and arylboron reagents were cross-coupled using this method. Arylation of optically active substrates derived from amino acids also provides a potential route for preparing non-proteinogenic amino acids.

Ligand-enabled methylene C(sp3)-H bond activation with a Pd(II) catalyst.

Project description:Pd(II) insertion into β-methylene C(sp(3))-H bonds was enabled by a mutually repulsive and electron-rich quinoline ligand. Ligand tuning led to the development of a method that allows for installation of an aryl group on a range of acyclic and cyclic amides containing β-methylene C(sp(3))-H bonds.

Palladium-catalyzed hydroalkylation of styrenes with organozinc reagents to form carbon-carbon sp3-sp3 bonds under oxidative conditions.

Project description:An unconventional route for the formation of sp(3)-sp(3) C-C bonds from various styrenes and an organozinc reagent in a formal alkene hydroalkylation process is detailed. Mechanistically, this process is proposed to proceed by initial transmetalation followed by formation of a Pd-H species, which is subsequently trapped by the styrene.

Pd(II)-catalyzed olefination of sp3 C-H bonds.

Project description:The first Pd(II)-catalyzed sp(3) C-H olefination reaction has been developed using N-arylamide directing groups. Following olefination, the resulting intermediates were found to undergo rapid 1,4-addition to give the corresponding gamma-lactams. Notably, this method was effective with substrates containing alpha-hydrogen atoms and could be applied to effect methylene C-H olefination of cyclopropane substrates.

Ligand-Enabled ?-C(sp3 )-H Olefination of Free Carboxylic Acids.

Project description:We report the ligand-enabled C-H activation/olefination of free carboxylic acids in the ?-position. Through an intramolecular Michael addition, ?-lactones are obtained as products. Two distinct ligand classes are identified that enable the challenging palladium-catalyzed activation of free carboxylic acids in the ?-position. The developed protocol features a wide range of acid substrates and olefin reaction partners and is shown to be applicable on a preparatively useful scale. Insights into the underlying reaction mechanism obtained through kinetic studies are reported.

Auxiliary-assisted palladium-catalyzed arylation and alkylation of sp2 and sp3 carbon-hydrogen bonds.

Project description:We have developed a method for auxiliary-directed, palladium-catalyzed beta-arylation and alkylation of sp(3) and sp(2) C-H bonds in carboxylic acid derivatives. The method employs a carboxylic acid 2-methylthioaniline- or 8-aminoquinoline amide substrate, aryl or alkyl iodide coupling partner, palladium acetate catalyst, and an inorganic base. By employing 2-methylthioaniline auxiliary, selective monoarylation of primary sp(3) C-H bonds can be achieved. If arylation of secondary sp(3) C-H bonds is desired, 8-aminoquinoline auxiliary may be used. For alkylation of sp(3) and sp(2) C-H bonds, 8-aminoquinoline auxiliary affords the best results. Some functional group tolerance is observed and amino- and hydroxy-acid derivatives can be functionalized. Preliminary mechanistic studies have been performed. A palladacycle intermediate has been isolated, characterized by X-ray crystallography, and its reactions have been studied.
