Direct synthesis of 3-arylpropionic acids by tetraphosphine/palladium catalysed Heck reactions of aryl halides with acrolein ethylene acetal

Through the use of [PdCl(C3H5)]2/Cis,cis, cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane as a catalyst, a range of aryl bromides undergoes Heck reaction with acrolein ethylene acetal. With this acetal, the selective formation of 3-arylpropionic acids/esters was observed. The functional group tolerance on the aryl halide is remarkable; substituents such as fluoro, methyl, methoxy, acetyl, formyl, benzoyl, nitro or nitrile are tolerated. Furthermore, this catalyst can be used at low loading, even for reactions of sterically hindered aryl bromides. Graphical Abstract.

Fabrication and Application of Graphene Supported Diimine-Palladium Complex Catalyst for Organic Synthesis

In this paper, a diimine palladium complex with suitable steric hindrance of isopropyl groups and electron supply provides excellent protection for palladium active centers was synthesized and anchored on graphene oxide (GO) to obtain a reusable heterogeneous catalyst (Pd-DI@GO). The XPS results confirmed the effective loading of palladium and the interaction between palladium and ligand. The ICP-AES data verified the Pd content of catalyst was 5.04 wt% and confirmed extremely small amount Pd leaching in Suzuki reaction (<1 ppm). The Pd-DI@GO can catalyze Suzuki reaction under milder conditions and afford 39 reactants with high yields (79%?99%). It can achieve a yield as high as 99% with heterocyclic compound reactants which can poison the catalyst. The yields of double and triple substitutions are also impressive (70?92%). The Pd-DI@GO can catalyze the C?H direct arylation reaction efficiently, affording 22 reactants with superior yields (>85%). Notably, the Pd-DI@GO can be recycled after Suzuki reaction via filtration or centrifugation easily, presenting a yield above 90% for the 4th run.

Modular ipso/ ortho Difunctionalization of Aryl Bromides via Palladium/Norbornene Cooperative Catalysis

Palladium/norbornene (Pd/NBE) cooperative catalysis has emerged as a useful tool for preparing poly substituted arenes; however, its substrate scope has been largely restricted to aryl iodides. While aryl bromides are considered as standard substrates for Pd-catalyzed cross coupling reactions, their use in Pd/NBE catalysis remains elusive. Here we describe the development of general approaches for aryl bromide-mediated Pd/NBE cooperative catalysis. Through careful tuning the phosphine ligands and quenching nucleophiles, ortho amination, acylation and alkylation of aryl bromides have been realized in good efficiency. Importantly, various heteroarene substrates also work well and a wide range of functional groups are tolerated. In addition, the utility of these methods has been demonstrated in sequential cross coupling/ortho functionalization reactions, consecutive Pd/NBE-catalyzed difunctionalization to construct penta-substituted aromatics and two-step meta functionalization reactions. Moreover, the origin of the ligand effect in ortho amination reactions has been explored through DFT studies. It is expected that this effort would significantly expand the reaction scope and enhance the synthetic potential for Pd/NBE catalysis in preparing complex aromatic compounds.

Suzuki-Miyaura cross-coupling of potassium alkoxyethyltrifluoroborates: Access to aryl/heteroarylethyloxy motifs

The introduction of an alkoxyethyl moiety onto aromatic substructures has remained a long-standing challenge for synthetic organic chemists. The main reasons are the inherent instability of alkoxyethylmetallic species and the lack of general procedures to access them. A new method utilizing a cross-coupling strategy based on the exceptional properties of organotrifluoroborates has been developed, and the method allows an easy and efficient installation of this unit on a broad range of aryl and heteroaryl bromides.

Conformationally restricted homotryptamines. Part 4: Heterocyclic and naphthyl analogs of a potent selective serotonin reuptake inhibitor

A series of hybrid molecules containing the cyclopropylmethylamino side chain found in homotryptamine (1S,2S)-2c and an isosteric heteroaryl or naphthyl core were prepared and their binding affinities for the human serotonin transporter determined. The most potent isosteres were CN-substituted naphthalenes. These results demonstrate that isosteric aromatic cores which lack an H-bond donor site may be substituted for the indole nucleus without substantial loss in hSERT binding.

Direct alpha-arylation of ethers through the combination of photoredox-mediated C-H functionalization and the minisci reaction

The direct alpha-arylation of cyclic and acyclic ethers with heteroarenes has been accomplished through the design of a photoredox-mediated C – H functionalization pathway. Transiently generated alpha-oxyalkyl radicals, produced from a variety of widely available ethers through hydrogen atom transfer (HAT), were coupled with a range of electron-deficient heteroarenes in a Minisci-type mechanism.
