Continuous-flow synthesis of 1-substituted benzotriazoles from chloronitrobenzenes and amines in a C-N bond formation/hydrogenation/ diazotization/cyclization sequence

Two approaches have been developed for the regiospecific continuous-flow synthesis of 1-substituted benzotriazoles. They begin with either an S NAr reaction at high temperature or Pd catalysis and involve consecutive multiphase processes, allowing the multistep synthesis of benzotriazoles to take place in an efficient manner (see picture).

Enantioselective functionalization of radical intermediates in redox catalysis: Copper-catalyzed asymmetric oxytrifluoromethylation of alkenes

Something radical: An efficient enantioselective oxytrifluoromethylation of alkenes has been developed using a copper catalyst system. Mechanistic studies are consistent with a metal-catalyzed redox radical addition mechanism in which a C-O bond is formed by the copper-mediated enantioselective trapping of a prochiral alkyl radical intermediate derived from the initial trifluoromethyl radical addition.

Anti-Markovnikov Hydroamination of Unactivated Alkenes with Primary Alkyl Amines

We report here a photocatalytic method for the intermolecular anti-Markovnikov hydroamination of unactivated olefins with primary alkyl amines to selectively furnish secondary amine products. These reactions proceed through aminium radical cation (ARC) intermediates and occur at room temperature under visible light irradiation in the presence of an iridium photocatalyst and an aryl thiol hydrogen atom donor. Despite the presence of excess olefin, high selectivities are observed for secondary over tertiary amine products, even though the secondary amines are established substrates for ARC-based olefin amination under similar conditions.

Mild and Functional Group Tolerant Method for Tandem Palladium-Catalyzed Carbocyclization-Coupling of ?-Acetylenic beta-Ketoesters with Aryl Bromides and Chlorides

We report a new protocol for the annulative difunctionalization of acetylenes via tandem carbocyclization-coupling of ?-acetylenic beta-ketoesters with aryl and heteroaryl bromides and chlorides catalyzed by the palladium species derived from an air- and moisture-stable palladacyclic precatalyst. In the tandem process, the palladium complex combines appropriate carbophilic Lewis acidity and redox activity to catalyze two mechanistically distinct reactions – nucleophilic addition of the enolate to unactivated alkyne, followed by C-C coupling. We found that a broad range of electronically varied aryl and heteroaryl bromides and chlorides underwent this reaction with various ?-acetylenic beta-ketoesters, providing corresponding substituted vinylidenecyclopentanes in high yield with excellent functional group tolerance.

Continuous-Flow Synthesis of Biaryls by Negishi Cross-Coupling of Fluoro- and Trifluoromethyl-Substituted (Hetero)arenes

A continuous-flow method for the regioselective arylation of fluoroarenes and fluoropyridines has been developed. The telescoped procedure reported here consists of a three-step metalation, zincation, and Negishi cross-coupling sequence, providing efficient access to a variety of functionalized 2-fluorobiaryl products. Precise temperature control of the metalation step, made possible by continuous-flow technology, allowed for the efficient preparation of the arylated products in high yields and short residence times. Additionally, several examples of the regioselective arylation of benzotrifluoride derivatives are also provided.

Palladium-Catalyzed One-Pot Synthesis of 5-(1-Arylvinyl)-1H-benzimidazoles: Overcoming the Limitation of Acetamide Partners

A new one-pot palladium-catalyzed process between N-tosylhydrazones, N-(dihalophenyl)-imidates, and amines was designed. This reaction involves Barluenga cross-coupling and N-arylation followed by cyclization to produce functionalized benzimidazoles. During this transformation, one C=C bond and two C=N bonds were created by a single palladium-catalyzed reaction. Depending on the starting materials, a library of 5-(1-arylvinyl)-1H-benzimidazoles was synthesized. Among several arylvinylbenzimidazole derivatives evaluated, one compound exhibits excellent antiproliferative activity in the nanomolar concentration range against human colon carcinoma cell lines (HCT-116) and human lung adenocarcinoma epithelial cell lines (A549).

Efficient and Functional-Group-Tolerant Synthesis of Substituted Furans through the Pd-Catalyzed 5-exo-dig Cyclization/Coupling of gamma-Acetylenic beta-Keto Esters with (Hetero)Aryl Bromides

Improved synthesis of icosahedral carboranes containing exopolyhedral B?C and C?C bonds

Carboranes are boron-rich molecular clusters possessing electronic characteristics that allow for orthogonal approaches to vertex-selective modifications. We report improved functionalization methods utilizing orthogonal chemistry to achieve efficient substitution at electron-rich B-vertices and electron-poor C-vertices of carborane. Functionalization of B-vertices with alkyl and (hetero)aryl groups using the corresponding Grignard reagents has been improved through the use of a Pd-based precatalyst featuring an electron-rich biaryl phosphine ligand, resulting in reduced reaction times. Importantly, this method is tolerant towards alkyl-based Grignard reagents containing beta-hydrogens. Furthermore, a transition metal-free approach to the substitution of carborane C-vertices with (hetero)aryl substrates has been developed under nucleophilic aromatic substitution (SNAr) conditions. The selective substitution of carboranes afforded by these methods holds potential for the rational synthesis of heterofunctionalized boron clusters with substituents on both boron and carbon-based vertices.
