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. The latter process was studied in detail by VT-NMR experiments using [Cu(IPr)(OtBu)] and 4-CF3-C6H4Bpin as an example, revealing the formation of an adduct (A) as a reaction intermediate. 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.

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.

Synthetic Route of C21H14Br4O5S. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide, is researched, Molecular C21H14Br4O5S, CAS is 76-60-8, about The Apoptosis Mechanism of Epirubicin Combined with BCG on Human Bladder Cancer Cells.

The purpose of our study was to explore the combination effect of epirubicin and Bacillus Calmette Guerin (BCG) and its mechanism. Bladder cancer is a threat to human health worldwide. Commonly used chemotherapy drugs and biotherapy have significant therapeutic effects on bladder cancer, but the mechanism and combined effects are still unclear. To evaluate the anti-cancer effect of epirubicin combined with BCG on human bladder cancer cells, our studies were carried out. The viability of human bladder cancer cells with epirubicin and/or BCG treatments was examined by Cell Counting Kit-8 (CCK-8) assay. Apoptosis and cell cycle phase were determined by flow cytometry anal. Pre-apoptosis factors of caspase-3, p53, B-cell lymphoma 2 associated X protein (Bax) and anti-apoptosis factor of B-cell lymphoma 2 (Bcl-2) were detected by western blot. The viability of human bladder cancer with epirubicin or BCG treatment was decreased and the viability with epirubicin combined with BCG treatment was decreased more, which were determined by CCK-8 assay. Both epirubicin and BCG increased the apoptosis rate of human bladder cancer and arrested more cells into G0/G1 phase, which were tested by flow cytometry. The expression of caspase-3, p53 and Bax was increased and the expression of Bcl-2 was decreased with epirubicin treatment on human bladder cells, which were analyzed by western blot. The expression of caspase-3 and p53 was increased with BCG treatment, which was examined by western blot. Epirubicin induced apoptosis in human bladder cancer cells by up-regulating the expression of proapoptotic factors (caspase-3, p53 and Bax) and down-regulating the expression of anti-apoptotic factor (Bcl-2). BCG promoted apoptosis of human bladder cancer cells by up-regulating the expression of caspase-3 and p53. BCG plays a potential role at the time of the combination of epirubicin and BCG on bladder cancer cells in early stage. Both epirubicin and BCG affected cell cycle distribution via arresting more bladder cancer cells at G0/G1 phase, which ultimately led bladder cancer proliferation in vitro and promoted apoptosis.

Computed Properties of C12H9N3. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 2-(Pyridin-4-yl)-1H-benzo[d]imidazole, is researched, Molecular C12H9N3, CAS is 2208-59-5, about Syntheses and crystal structures of four silver(I) complexes based on 2-(4-pyridyl)benzimidazole.

Four new Ag(I) complexes constructed with 2-(4-pyridyl)benzimidazole, namely, [Ag(PyBIm)(H2O)]·NO3 (1), [Ag(PyBIm)(H2O)]·ClO4 (2), [Ag2(PyBIm)2](SiF6)·2H2O (3) and [Ag(PyBIm)(HBDC)] (4) (PyBIm = 2-(4-pyridyl)benzimidazole, BDC = 1,3-benzenedicarboxylate) were synthesized and characterized by x-ray crystallog. All the Ag(I) atoms in complexes 1-4 are bridged by the different PyBIm ligands via NPy and NBIm into 1-dimensional zigzag chains. The anions do not coordinate to the Ag(I) atoms and only act as counterions in complexes 1-3. Due to the anions, different H bonding systems are found in those three compounds, resulting in the different crystal packing. Through H bonding interactions, the structures of complexes 1-3 display a double layer, a three-dimensional framework and a novel double chain, resp. In complex 4, the HBDC- anions act not only as a counterion, but also as bridging ligands, which lead the zigzag [Ag2(PyBIm)2]∞ chain into a two-dimensional undulating sheet. The sheets are connected through H-bonding as well as π-π interactions into a three-dimensional framework. The thermal stabilities of the four complexes and anion exchange properties of complexes 2 and 3 were also studied.

Mutagenic agents such as aromatic amines undergo metabolic activation and produce DNA adducts at C8 position of guanine bases. N-2-acetylaminofluorene (AAF) generates different mutational outcomes when placed at G1, G2, and G3 of a NarI sequence (-G1G2CG3CC/T-). These outcomes are dictated by the conformations adopted by these adducts. Detection of such lesions is of considerable interest owing to their hazardous effects. Here, we report the synthesis of three cyclometalated [Ir(L)2dppz]+ complexes (L = 2-phenylpyridine (ppy) 1; benzo[h]quinoline (bhq) 2; 2-phenylquinoline (pq) 3; dppz = dipyrido[3,2-a:2,3-c]phenazine) and their interaction with AAF adducted NarI DNA. Remarkably, complexes 1 and 2 displayed dominant 3LC transition characteristic of polar environment despite binding to the adducted sites. On the other hand, complex 3 binds to NarI sequences and behaves as a luminescent reporter for AAF-modified DNA. The results reported here emphasize that mol. light switching phenomenon can be stimulated by switching ancillary ligands and might act as potential probes for covalent-DNA defects.
