Bicyclic Bridgehead Phosphoramidite-Based Hybrid Diphosphorus Ligands: Design, Synthesis, and Application in Catalytic Asymmetric Hydrogenation

A strategy for chiral ligand design has been developed that allows for incorporation of an achiral bicyclic bridgehead phosphoramidite to generate a class of hybrid diphosphorus ligands for high activity and asymmetric control. Using this concept, a series of chiral phosphine-phosphoramidite ligands bearing the sole chirality at the ligand backbone have been prepared and successfully employed in the Rh-catalyzed asymmetric hydrogenation of 2-vinylanilides for the synthesis of optically active anilines bearing an ortho-tertiary benzylic stereocenter.

Selectfluor-mediated mono-C–H activation: The syntheses of mono-ortho-substituted anilides

The C–H activation of aryl amide using readily available Pd(OAc)2 in the presence of selectfluor is reported. The highly mono-selective introduction of sp2 hybridized functional groups have been realized. A broad range of aryl-, alke

Palladium Catalyzed Direct Acylation of Iodo-Acetanilides/Iodo-Phenyl Acetates: Domino One-Pot Synthesis of 2-Quinolinones

Pd-catalyzed direct acylation reaction of iodoacetanilides/iodophenyl acetates with aldehydes is presented. Simple, bench-top aldehydes were used as non-toxic acylating agents. This protocol comprises direct coupling with aldehydes without activating the carbonyl group and without directing group assistance. The strategy was applied to a domino one-pot synthesis of 2-quinolinones through acylation and intramolecular aldol condensation. Significantly, the strategy was extended to the domino one-pot synthesis of drugs and bioactive compounds.

Activation of C-H Activation: The Beneficial Effect of Catalytic Amount of Triaryl Boranes on Palladium-Catalyzed C-H Activation

Herein we report a novel approach to the acceleration of palladium-catalyzed C-H activation reactions. We demonstrated that the utilization of electron-deficient triaryl boranes as Lewis acidic cocatalysts of palladium enables the directed cross dehydrogenative coupling of aldehydes and anilides under mild reaction conditions. Study of the kinetic profile of the transformation reveals a unique, unexpectedly long induction period of the transformation.

Palladium-catalyzed C-H bond acylation of acetanilides with benzylic alcohols under aqueous conditions

Palladium-catalyzed dehydrogenative coupling reactions between acetanilides and benzylic alcohols under aqueous conditions are reported. A wide range of benzophenone derivatives could be obtained in good to excellent yields up to 98 %. Mechanism studies showed that a bimetallic palladium cyclopalladated complex might be involved in the catalysis.

Dual role of acetanilides: Traceless removal of a directing group through deacetylation/diazotation and palladium-catalyzed C-C-coupling reactions

The acetamide group enables regioselective oxidative ortho-C-H activation reactions, such as Pd-catalyzed acylation. The synthetic utility of these transformations can be significantly enhanced by using the acetamide as a quasi-leaving group in a subsequent conventional Pd-catalyzed coupling or cross-coupling reaction. The concept is illustrated herein for the synthesis of o-alkenyl- and o-arylphenones, which have potential for the synthesis of arylated aromatic heterocycles.

Merging Photoredox with Palladium Catalysis: Decarboxylative ortho-Acylation of Acetanilides with α-Oxocarboxylic Acids under Mild Reaction Conditions

A room temperature decarboxylative ortho-acylation of acetanilides with α-oxocarboxylic acids has been developed via a novel Eosin Y with Pd dual catalytic system. This dual catalytic reaction shows a broad substrate scope and good functional group tolera

A one-pot process for palladium catalyzed direct C-H acylation of anilines in water using a removable ortho directing group

A new mild, practical method for the synthesis of aminobenzophenone derivatives through a three step one-pot reaction sequence involving acylation of anilines, palladium catalyzed cross-dehydrogenative coupling of the formed anilides and the hydrolytic cleavage is reported. The full reaction sequence was performed under aqueous conditions.

Palladium-catalyzed direct oxidative ortho-acylation of anilides with toluene derivatives

Direct oxidative ortho-acylation reaction of anilides with toluene derivatives in the presence of palladium acetate using tert-butyl hydroperoxide as an oxidant was developed. A broad range of diaryl ketones was obtained in good to excellent yields (up to 95%). The plausible mechanism was also proposed.

Toluene derivatives as simple coupling precursors for cascade palladium-catalyzed oxidative C-H bond acylation of acetanilides

A palladium-catalyzed cascade cross-coupling of acetanilide and toluene for the synthesis of ortho-acylacetanilide is described. Toluene derivatives can act as effective acyl precursors (upon sp3-C-H bond oxidation by a Pd/TBHP system) in the oxidative coupling between two C-H bonds. This dehydrogenative Pd-catalyzed ortho-acylation proceeds under mild reaction conditions.
