Like 301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride. In a document type is Article, introducing its new discovery.

(+)-Ryanodine (1) is the ester derivative of 1H-pyrrole-2-carboxylic acid and the complex terpenoid (+)-ryanodol (2), which possesses eleven contiguous stereogenic centers on the ABCDE-ring system. Compound 1 is known to be a potent modulator of intracellular calcium release channels, whereas the activity of 2 is significantly weaker. To chemically construct 1, the multiple oxygen functional groups must be installed on the fused pentacycle in stereoselective fashions and the extremely hindered C3-hydroxy group must be acylated in a site-selective manner. First, the total synthesis of 2 was accomplished by introducing the five stereocenters from the previously prepared enantiopure ABDE-ring 7. Stereoselective construction of the C3-secondary, C2- and C6-tertiary alcohols was achieved by three nucleophilic reactions. The C9- and C10-trisubstituted carbon centers were regio- and stereoselectively introduced by hydroboration/oxidation of the six-membered C-ring, which was formed by the ring-closing metathesis reaction. Direct esterification of the C3-alcohol with pyrrole-2-carboxylic acid proved unsuccessful; therefore, we developed a new, two-step protocol for attachment of the pyrrole moiety. The C3-hydroxy group was first converted into the less sterically cumbersome glycine ester, which was then transformed into the pyrrole ring through condensation with 1,3-bis(dimethylamino)allylium tetrafluoroborate. This procedure resulted in the first total synthesis of 1.

The feasibility of devising a solid support mediated approach to multimodal Ru(II)-peptide nucleic acid (PNA) oligomers is explored. Three Ru(II)-PNA-like monomers, [Ru(bpy)2(Cpp-L-PNA-OH)]2+ (M1), [Ru(phen) 2(Cpp-L-PNA-OH)]2+ (M2), and [Ru(dppz)2(Cpp-L- PNA-OH)]2+ (M3) (bpy = 2,2?-bipyridine, phen = 1,10-phenanthroline, dppz = dipyrido[3,2-a:2?,3?-c]phenazine, Cpp-L-PNA-OH = [2-(N-9-fluorenylmethoxycarbonyl)aminoethyl]-N-[6-(2-(pyridin- 2yl)pyrimidine-4-carboxamido)hexanoyl]-glycine), have been synthesized as building blocks for Ru(II)-PNA oligomers and characterized by IR and 1H NMR spectroscopy, mass spectrometry, electrochemistry and elemental analysis. As a proof of principle, M1 was incorporated on the solid phase within the PNA sequences H-g-c-a-a-t-a-a-a-a-Lys-NH2 (PNA1) and H-P-K-K-K-R-K-V-g-c-a-a-t-a-a-a-a-lys-NH2 (PNA4) to give PNA2 (H-g-c-a-a-t-a-a-a-a-M1-lys-NH2) and PNA3 (H-P-K-K-K-R-K-V-g-c-a-a-t- a-a-a-a-M1-lys-NH2), respectively. The two Ru(II)-PNA oligomers, PNA2 and PNA3, displayed a metal to ligand charge transfer (MLCT) transition band centered around 445 nm and an emission maximum at about 680 nm following 450 nm excitation in aqueous solutions (10 mM PBS, pH 7.4). The absorption and emission response of the duplexes formed with the cDNA strand (DNA: 5?-T-T-T-T-T- T-T-A-T-T-G-C-T-T-T-3?) showed no major variations, suggesting that the electronic properties of the Ru(II) complexes are largely unaffected by hybridization. The thermal stability of the PNA?DNA duplexes, as evaluated from UV melting experiments, is enhanced compared to the corresponding nonmetalated duplexes. The melting temperature (Tm) was almost 8 C higher for PNA2?DNA duplex, and 4 C for PNA3?DNA duplex, with the stabilization attributed to the electrostatic interaction between the cationic residues (Ru(II) unit and positively charged lysine/arginine) and the polyanionic DNA backbone. In presence of tripropylamine (TPA) as co-reactant, PNA2, PNA3, PNA2?DNA and PNA3?DNA displayed strong electrochemiluminescence (ECL) signals even at submicromolar concentrations. Importantly, the combination of spectrochemical, thermal and ECL properties possessed by the Ru(II)-PNA sequences offer an elegant approach for the design of highly sensitive multimodal biosensing tools.

We demonstrate the synthesis and characterization of the solution conformations of a collection of functionalized spiroligomer-based macrocycles. These macrocycles contain 14 independently controllable stereocenters and four independently controllable functional groups on a highly preorganized scaffold. These molecules are being developed to display complex, preorganized surfaces for binding proteins and to create enzyme-like active sites. In this work, we demonstrate the convergent synthetic approach to this new class of macrocycles and demonstrate that the conformational properties of these molecules can be changed by altering the configuration stereocenters within the backbone.

A novel microwave-assisted synthetic method has been used to synthesise a series of mixed ligand ruthenium(II) compounds containing diimine as well as bidentate thiosemicarbazone ligands. The compounds contain the diimine 1,10-phenanthroline (phen) or 2,2?-bipyridine (bpy) and the thiosemicarbazone is derived from 9-anthraldehyde. Based on elemental analyses and spectroscopic data, the compounds are best formulated as [(phen) 2Ru(thiosemicarbazone)](PF6)2 and [(phen) 2Ru(thiosemicarbazone)](PF6)2 where thiosemicarbazone = 9-anthraldehydethiosemicarbazone, 9-anthraldehyde-N(4)- methylthiosemicarbazone, and 9-anthraldehyde-N(4)-ethylthiosemicarbazone. Fluorescence competition studies with ethidium bromide, along with viscometric measurements suggests that the complexes bind calf thymus DNA (CTDNA) relatively strongly via an intercalative mode possibly involving the aromatic rings of the diimine ligands. The complexes show good cytotoxic profiles against MCF-7 and MDA-MB-231 (breast adenocarcinoma) as well as HCT 116 and HT-29 (colorectal carcinoma) cell lines. The Royal Society of Chemistry 2009.

Treatment of [(eta6-C6H6)RuCl2]2 or [(eta6-p-cymene)RuCl2]2 with two equiv. of L-methionine in the presence of AgNO3 and NaOMe gave mononuclear ruthenium(II) complexes [(eta6-C6H6)Ru(L-met)](NO3) (1) and [(eta6-cymene)Ru(L-met)](NO3) (2), respectively. Interactions between equal equiv. of L-methionine and [Ru(CO)2Cl2]n, [Ru(bpy)2Cl2]·2H2O (bpy = 2,2?-bipyridine), [Ru(NO)(PPh3)2Cl3], (Et4N)[Ru(CH3CN)2Cl4] or cis-[Ru(DMSO)4Cl2] (DMSO = dimethylsulfoxide) resulted in isolation of the expected ruthenium complexes [(CO)2Ru(L-met)Cl] (3), [(bpy)2Ru(L-met)]Cl (4), [Ru(L-met)(NO)(PPh3)Cl]Cl (5), [Ru(L-met)(CH3CN)Cl2] (6) and [Ru(L-met)(DMSO)2Cl] (7), respectively. Reaction of [Ru(COD)Cl2]2 (COD = 1,5-cyclooctadiene) with L-methionine gave a dinuclear ruthenium complex [(COD)Ru(mu-S-L-met)(mu-Cl)RuCl(L-metNMe2)] (8). Complexes 1?8 were characterized by microanalyses, IR, NMR and UV?vis spectroscopies. The structures of complexes 1, 2, 4 and 8 have been unambiguously established by single-crystal X-ray crystallography. The photocatalytic properties for hydrogen production by water splitting of complexes 1, 2, 4 and 8 under visible light (lambda > 420 nm) were also investigated.

An olefin metathesis catalyst (8) bearing a hemilabile N-heterocyclic carbene (NHC) ligand with four methoxyethoxy arms was synthesized and analyzed by X-ray crystallography and NMR spectroscopy. The solid-state structure of the catalyst reveals that one of the aromatic rings is rotated toward the plane of the NHC heterocycle, which enables one ortho-O?Ru coordination. Ring-closing metathesis (RCM) activity was tested at low catalyst loadings. Catalyst 8 was found to display a significant rate enhancement relative to the commercial catalyst 3 but offered no improvement in turnover numbers (TON). The solid-state structure of the catalyst’s major degradation product (9) in the presence of 1-hexene reveals a dinuclear compound containing a bridging methylidene (Ru-CH2-Ru), indicating that the methoxyethoxy arms may not be strong enough to stabilize the (NHC)RuCl2(?CH2) catalyst resting state.

We report here new examples of enantiomerically pure monodendate phosphinite ligands containing both a ferrocene moiety and NH bridging moiety adjacent to the stereocenter, as well as their ruthenium(II) dichloro complexes. The phosphinites based on ferrocenyl moiety possessing stereogenic center have been screened as ligands for ruthenium(II)-catalyzed transfer hydrogenation of aromatic ketones to give corresponding secondary alcohols using iso-PrOH as the hydrogen source in the presence of NaOH. Up to 99% conversion with 97% ee was obtained in the transfer hydrogenation of acetophenone derivatives. Furthermore, the catalytic properties of these catalysts based on ferrocenyl-phosphinite backbone are also discussed briefly. The structures of these ligand and their corresponding complexes have been elucidated by a combination of multinuclear NMR spectroscopy, IR spectroscopy and elemental analysis.
