C-Glycosides are metabolically stable mimics of natural O-glycosides and are expected to be useful tools for investigation of the biol. functions of glycans. Here, we describe the synthesis of a series of aryl and vinyl C-glycosides by stereoinvertive sp3-sp2 cross-coupling reactions of 2-deoxyglycosyl boronic acid derivatives with aryl or vinyl halide, mediated by a photoredox/nickel dual catalytic system. Hydrogenation of the vinyl C-glycosides afforded C-linked 2′-deoxydisaccharide analogs.

The treatment of several 2-diphenylphosphinoimidazoles with Pd(II) salts generates monosubstituted N-H NHC-Pd complexes via insertion into the C-P bond is reported. Removal of the N-H proton in situ leads to anionic (X-type) or imidazolyl-Pd complexes that are highly stable and catalytically active, achieving up to 340,000 turnovers at 1 ppm catalyst loading in Suzuki-Miyaura reactions. DFT-calculated Tolman electronic parameters for the sterically small ligands suggest that these ligands are significantly more donating than traditional NHCs, which provides a rationale for rapid cross-coupling catalysis. Excellent reactivity is also demonstrated in Sonogashira reactions.

Ruthenium(II) biscarboxylate complexes enabled the selective alkylation of C-H and C-C bonds at the ortho- or meta-position. Ortho-C-H alkylations were achieved with 4-, 5-, and 6-membered halocycloalkanes. Furthermore, the judicious choice of the directing group allowed for a full control of ortho-/meta-selectivities. Detailed mechanistic studies by experiment and computation were performed and provided strong support for an oxidative addition/reductive elimination process for ortho-alkylations, while a homolytic C-X cleavage was operative for the meta-selective transformations.

Hepatocellular carcinoma (HCC) poses a serious threat to people′s health worldwide. Artesunate (ART), one of the classical antimalarial drugs, has recently been shown to exert significant cytotoxicity in various cancers, but its bioavailability is low. Cyclometalated iridium(III) complexes have emerged as a promising class of anticancer therapeutic agents. Herein, through conjugation of two of them, three novel Ir(III)-ART conjugates, [Ir(C-N)2(bpy-ART)](PF6) (bpy = 2,2′-bipyridine, C-N = 2-phenylpyridine (ppy, Ir-ART-1), 2-(2-thienyl)pyridine (thpy, Ir-ART-2), and 2-(2,4-difluorophenyl)pyridine (dfppy, Ir-ART-3)) have been synthesized, and their potential as anti-HCC agents was evaluated. We demonstrate that Ir-ART-1-3 display higher cytotoxicity against HCC cell lines than normal liver cells, and they can especially locate to mitochondria of HepG2 cells and induce a series of mitochondria-mediated apoptosis events. Moreover, Ir-ART-1-3 can regulate the cell cycle and inhibit metastasis of HepG2 cells. Finally, in vivo antitumor evaluation also demonstrates the inhibitory activity of Ir-ART-1 on tumor growth. Taken together, these Ir(III)-ART conjugates have the potential to become drug candidates for future anti-HCC treatments.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called NHC-stabilized copper(I) aryl complexes and their transmetalation reaction with aryl halides, published in 2020-07-15, which mentions a compound: 141556-42-5, Name is 1,3-Bis(2,4,6-trimethylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene, Molecular C21H24N2, Reference of 1,3-Bis(2,4,6-trimethylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene.

The authors report herein the synthesis, spectroscopic and structural characterization of NHC-stabilized Cu aryl complexes (NHC = N-heterocyclic carbene) [Cu(NHC)(Ar)] 1-5, 7-22 with various aryl ligands (4-Me-C6H4, 4-MeO-C6H4, 2,4,6-Me3C6H2, C6F5, 4-CF3-C6H4, (3,5-(CF3)2C6H3), 2,3,5,6-Me4-C6H, 2,6-iPr2-C6H3, C6Me5) and NHCs (IiPr, ItBu, IMes, IPr). Three different synthetic routes were used to obtain these complexes: (i) reaction of a Cu(I) aryl complex with a free NHC; (ii) reaction of an NHC-stabilized Cu(I) chloride with a Grignard reagent, which is one important step in Kumada-Tamao-Corriu type cross-coupling reactions; and (iii) reaction of an NHC-stabilized Cu(I) alkoxide with an organoboronic ester, which represents an important step in Suzuki-Miyaura type cross-coupling reactions.

Also, the reactivity of the [Cu(NHC)(Ar)] complexes towards aryl halides was studied.

Author is Huo, Haohua; Gorsline, Bradley J.; Fu, Gregory C..

Stereochem. control in the construction of carbon-carbon bonds between an alkyl electrophile and an alkyl nucleophile is a persistent challenge in organic synthesis. Classical substitution reactions via SN1 and SN2 pathways are limited in their ability to generate carbon-carbon bonds (inadequate scope, due to side reactions such as rearrangements and eliminations) and to control stereochem. when beginning with readily available racemic starting materials (racemic products). Here, we report a chiral nickel catalyst that couples racemic electrophiles (propargylic halides) with racemic nucleophiles (β-zincated amides) to form carbon-carbon bonds in doubly stereoconvergent processes, affording a single stereoisomer of the product from two stereochem. mixtures of reactants.

Compound: 2-Phenylpyridine, is researched, Molecular C11H9N, CAS is 1008-89-5, about Selective Halogenation of Pyridines Using Designed Phosphine Reagents, the main research direction is regioselective halogenation pyridine phosphine phosphonium salt mol modeling; halopyridine preparation.Name: 2-Phenylpyridine.

Halopyridines are key building blocks for synthesizing pharmaceuticals, agrochems., and ligands for metal complexes, but strategies to selectively halogenate pyridine C-H precursors are lacking. We designed a set of heterocyclic phosphines that are installed at the 4-position of pyridines as phosphonium salts and then displaced with halide nucleophiles. A broad range of unactivated pyridines can be halogenated, and the method is viable for late-stage halogenation of complex pharmaceuticals. Computational studies indicate that C-halogen bond formation occurs via an SNAr pathway, and phosphine elimination is the rate-determining step. Steric interactions during C-P bond cleavage account for differences in reactivity between 2- and 3-substituted pyridines.
