(Chemical Equation Presented) Two ring or not to ring: Novel diruthenium olefin metathesis catalysts show a tendency to avoid oligomerization and favor cyclic dimerization when the distances between the ruthenium centers and between the diene extremities match (see scheme).

RNA editing by adenosine deamination is a form of epigenetic control of gene expression wherein the ADAR enzymes convert adenosine to inosine in RNA often changing the meaning of codons. The pre-mRNA for the 2c subtype of serotonin receptor (5-HT2cR) is shown here to support small molecule binding near known editing sites. Furthermore, a helix-threading peptide binds this site and inhibits the in vitro reaction of ADAR2 in an RNA-substrate selective manner. This is the first example of substrate-selective inhibition of editing by an RNA-binding small molecule and sets the stage for the development of new reagents capable of controlling gene function through manipulation of mRNA editing.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, you can also check out more blogs about301224-40-8

The scope of ruthenium (Ru)-catalyzed cross metathesis (CM) of allyl-decorated polyhedral oligomeric silsesquioxanes (POSS) was explored. A variety of different commercial and non-commercial ruthenium complexes were tested to determine that the nitro-activated Ru catalyst is optimal for this transformation. The reported transformation was used to prepare selected hybrid steroid-POSS compounds.

The ordered structures constructed from an aligner molecule 1o and conjugated polymers (CPs) were efficiently converted into the poly-pseudo-rotaxane structures by the template-assisted ring-closing olefin metathesis (RCM) of olefinic groups at the peripheral positions of 1o. Moreover, the poly-pseudo-rotaxane structures permitted the separation of the crystalline ordered assemblies of CP by size exclusion chromatography and the preservation of the sheet morphologies after the treatment with trifluoroacetic acid. The morphologies and the periodicities of assemblies were also maintained after the retrieving treatments. Copyright

The synthesis of new ruthenium-based catalysts applicable for both homogeneous and heterogeneous metathesis is described. Starting from the Hoveyda-Grubbs first generation (1) and the Hoveyda-Grubbs second generation (2) catalysts the homogeneous catalysts [RuCl((RO)3Si-C3H6-N(R?)-CO-C3F6-COO)({double bond, long}CH-o-O-iPr-C6H4)(SIMes)] (4: R = Et, R? = H; 5: R = R? = Me) (SIMes = 1,3-bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazol-2-ylidene) were prepared by substitution of one chloride ligand with trialkoxysilyl functionalized silver carboxylates (RO)3Si-C3H6-N(R?)-CO-C3F6-COOAg (3a: R = Et, R? = H; 3b: R = R? = Me). These homogeneous ruthenium-species are among a few known examples with mixed anionic ligands. Exchange of both chloride ligands afforded the catalysts [Ru((RO)3Si-C3H6-N(R?)-CO-C3F6-COO)({double bond, long}CH-o-O-iPr-C6H4)(SIMes)] (9: R = Et, R? = H; 11: R = R? = Me) and [Ru((RO)3Si-C3H6-N(R?)-CO-C3F6-COO)({double bond, long}CH-o-O-iPr-C6H4)(PCy3)] (8: R = Et, R? = H; 10: R = R? = Me). The reactivity of the new complexes was tested in homogeneous ring-closing metathesis (RCM) of N,N-diallyl-p-toluenesulfonamide and TONs of up to 5000 were achieved. Heterogeneous catalysts were obtained by reaction of 4, 5 and 8-11 with silica gel (SG-60). The resultant supported catalysts 4a, 5a, 8a-11a showed reduced activity compared to their homogenous analogues, but rival the activity of similar heterogeneous systems.

A document type is Article, introducing its new discovery.

New oxygen chelated ruthenium carbene complex containing carbonyl oxygen and ether oxygen has been developed. The X-ray structure of the complex showed that the carbonyl oxygen of the amide and the terminal oxygen of the benzylidene ether are both coordinated to the metal to give an octahedral structure. The catalytic activities of this new complex for olefin metathesis reactions were investigated and it exhibited excellent performances for the ring-closing metathesis (RCM) of diethyl diallymalonate at 30 C and even at 0 C. The initiation rate of the catalyst was higher than that for the Hoveyda catalyst ((H2IMes)(Cl)2Ru = C(H)(C6H 4-2-OiPr)) and it was also active for cross metathesis (CM).

A process of preparing an unsaturated alcohol (olefin alcohol), such as, a homo-allylic mono-alcohol or homo-allylic polyol, involving protecting a hydroxy-substituted unsaturated fatty acid or fatty acid ester, such as methyl ricinoleate, derived from a seed oil, to form a hydroxy-protected unsaturated fatty acid or fatty acid ester; homo-metathesizing or cross-metathesizing the hydroxy-protected unsaturated fatty acid or fatty acid ester to produce a product mixture containing a hydroxy-protected unsaturated metathesis product; and deprotecting the hydroxy-protected unsaturated metathesis product under conditions sufficient to prepare the unsaturated alcohol. Preferably, methyl ricinoleate is converted by cross-metathesis or homo-metathesis into the homo-allylic mono-alcohol 1-decene-4-ol or the homo-allylic polyol 9-octadecene-7,12-diol, respectively.

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 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.
