Recent advances in the application of heterogeneous nanocatalysts for sonogashira coupling reactions

Sonogashira coupling reactions demonstrates an efficient and facile methodology for C(sp)-C(sp2) bond formations via transition-metal-catalyzed processes and have found applications in a wide variety of areas including medicinal chemistry, agrochemistry, materials, electronics and synthesis of natural products, biologically active molecules, heterocycles, dendrimers and conjugated polymers or nanostructures. In recent years, nanosized heterogeneous catalysts have been widely studied for the above reactions due to thermal stability, reusability and high catalytic activities. In this review, we present an introduction to the subject of carbon-carbon bond formations and recent efforts in the preparation and application of heterogeneous nanocatalysts for Sonogashira coupling reactions. The scope, limitations, and green aspects of the reactions, convenient methods of preparation of heterogeneous nanocatalysts and their characterization have also been highlighted. These include metal nanoparticles, nanoclusters and nanocrystals, bimetallic, trimetallic and core-shell nanoparticles, polymersupported metal nanoparticles, carbon- or graphene-supported metal/metal oxide nanohybrids and metal-organic frameworks Pd catalysts. Numerous examples demonstrated the use of effective supports such as silica, SBA-15, MCM-41, BaO, Smopex, ZnO, celluloses, montmorillonite, Al2O3, chitosan and natural biomaterials in Sonogashira coupling reactions.

Palladium-catalyzed synthesis of 2,1?-disubstituted tetrahydrofurans from gamma-hydroxy internal alkenes. Evidence for alkene insertion into a Pd-O bond and stereochemical scrambling via beta-hydride elimination

Palladium-catalyzed reactions of gamma-hydroxy internal acyclic alkenes with aryl bromides afford 2,1?-disubstituted tetrahydrofurans in good yields with diastereoselectivities of 3-5:1, The analogous transformations of substrates bearing internal cyclic alkenes afford fused bicyclic and spirocyclic tetrahydrofuran derivatives in good yields with excellent diastereoselectivities (>20:1). A series of deuterium labeling experiments indicate that the origin of the modest diastereoselectivity in reactions of acyclic internal alkene substrates likely derives from a series of reversible beta-hydride elimination and sigma-bond rotation processes that occur following a rare intramolecular alkene syn-insertion into an intermediate Pd(Ar)(OR) complex. In addition, these studies shed light on the chemoselectivity of insertion, suggesting that the alkene inserts into the Pd-O bond in preference to the Pd-C bond.

Hydroxymethylation of Quinolines with Na2S2O8 by a Radical Pathway

Quinolines and isoquinolines were treated with Na2S2O8 in a mixture of methanol and water at 70 C to form hydroxymethylated quinolines and isoquinolines in good to moderate yields, under transition-metal-free conditions. The formed hydroxymethyl group was smoothly converted into aldehyde, ester, amide, bromomethyl, (N,N-diethylamino)methyl, cyano, and tetrazole groups, in good yields.

Photoredox Cross-Coupling: Ir/Ni Dual Catalysis for the Synthesis of Benzylic Ethers

Single-electron transmetalation has emerged as an enabling paradigm for the cross-coupling of Csp3 hybridized organotrifluoroborates. Cross-coupling of alpha-alkoxymethyltrifluoroborates with aryl and heteroaryl bromides has been demonstrated by employing dual catalysis with a combination of an iridium photoredox catalyst and a Ni cross-coupling catalyst. The resulting method enables the alkoxymethylation of diverse (hetero)arenes under mild, room-temperature conditions. (Chemical Equation Presented).

Novel pyridyl substituted 4,5-dihydro-[1,2,4]triazolo[4,3-a ]quinolines as potent and selective aldosterone synthase inhibitors with improved in vitro metabolic stability

CYP11B2 inhibition is a promising treatment for diseases caused by excessive aldosterone. To improve the metabolic stability in human liver miscrosomes of previously reported CYP11B2 inhibitors, modifications were performed via a combination of ligand-and structure-based drug design approaches, leading to pyridyl 4,5-dihydro-[1,2,4]triazolo[4,3-a]quinolones. Compound 26 not only exhibited a much longer half-life (t1/2 120 min), but also sustained inhibitory potency (IC50 = 4.2 nM) and selectivity over CYP11B1 (SF = 422), CYP17, CYP19, and a panel of hepatic CYP enzymes.

Palladium Charcoal-Catalyzed Suzuki-Miyaura Coupling to Obtain Arylpyridines and Arylquinolines

A phosphine ligand, such as PPh3 or 2-(dicyclohexylphosphino)biphenyl, is essential for the Pd/C-catalyzed Suzuki-Miyaura coupling of halopyridines and haloquinolines, although it has been reported that the reaction of phenyl chlorides can be catalyzed by nonprereduced Pd/C without any additives. In the reactions of bromopyridines, bromoquinolines, 2-chloropyridines, and 2-chloroquinolines, PPh3 was effective enough to provide coupling products in good yields. However, in the reactions of 3-chloropyridine, 4-chloropyridine, and 6-chloroquinoline, sterically hindered 2-(dicyclohexylphosphino)biphenyl was indispensable as a ligand.
