Under standard conditions the cross metathesis of allyl alcohols and methyl acrylate is accompanied by the formation of ketones, resulting from uncontrolled and undesired double bond isomerization. By conducting the CM in the presence of phenol, the catalyst loading and the reaction time required for quantiative conversion can be reduced, and isomerization can be suppressed. On the other hand, consecutive isomerization can be deliberately promoted by evaporating excess methyl acrylate after completing cross metathesis and by adding a base or silane as chemical triggers.

Ring-opening/ring-closing metathesis on cyclobutene-containing substrates with angular oxygen functionality provides a stereospecific introduction of 1,5-bis-dienes required for an anion-accelerated oxy-Cope rearrangement. The reaction sequence offers generally a stereocontrolled preparation of a variety of medium ring-containing bicyclic ring systems, while rearrangement to the bicyclo[7,3,0]dodecane (9-5) system leads to a mixture of olefin isomers.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, name: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium.

A new synthesis of the important amino acid 2-aminosuberic acid from aspartic acid is reported. The methodology involves the alternate preparation of (S)-2-aminohept-6-enoate ester as a building block and its diversification through a cross-metathesis reaction to prepare the title compounds. The utility of the protocol is demonstrated through the preparation of three suberic acid derivatives of relevance to the design and the synthesis of peptides of biological relevance.

The performance of cross-metathesis reactions between acrylate esters and olefins catalyzed by Grubbs catalysts have been enhanced by the simple addition of p-cresol. For example, the efficiency of the cross metathesis reaction between methyl acrylate and 1-decene catalyzed by 2 was significantly increased by addition of p-cresol to the reaction mixture, resulting in increased product yields and E/Z ratios.

Here, we report a simple and useful strategy for a series of C3-symmetric pi-conjugated and highly soluble spiro-annulated truxene derivatives. The role of substituent at C5, C10, C15, C2, C7, and C12 positions was studied. We observed that truxenes containing carbonyl groups showed red shift in the absorption maxima in comparison with compounds devoid of carbonyl group. Enhanced conjugation in these systems may be responsible for this red shift. It was observed that truxene derivatives with carbonyl moiety exhibited faster decay than other derivatives. Benzyl groups play some role in the excited state dynamics as decay becomes slower when the spiro moiety was replaced by benzyl group at C5, C10, and C15 positions. Additionally, we noticed the highest quantum yield in t-butanol solvent and least in acetonitrile.

Transannular ring-closing ene-yne metathesis of l-(omega -alkenyl)-1?-propargylferrocene derivatives affords the corresponding ferrocenophanes in good yields in the presence of the second-generation Grubbs Ru catalyst. The reaction is applicable to the preparation of [4]- and [5]ferrocenophanes. The ferrocenophanes obtained by the present reaction possess a conjugated diene functionality in the bridging side chain, and their further modification is attained via Diels-Alder cycloaddition with tetracyanoethylene or dimethyl acetylenedicarboxylate in a highly diastereoselective fashion.

The total synthesis of melleumin A (1), a novel cyclic depsipeptide isolated from the myxomycete Physarum melleum, and 3-epi-melleumin A (6) was achieved. Melleumin A-like compounds were also designed and synthesized; analysis of these melleumin A-like compounds showed moderate Wnt signal inhibition. Comparison of the inhibition activity of melleumin B and its three epimers, melleumin A, 3-epi-melleumin A and three melleumin A-like compounds led to further investigation of the structural conformation of the active molecules. The scaffold of melleumin is a potential target in the search for “peptide-like” Wnt signaling inhibitors.

Electric Literature of 246047-72-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a patent, introducing its new discovery.

Electrospray ionization mass spectrometry (ESI-MS) and subsequent MS/MS methods were used to study second-generation Grubbs catalysts 2 and 3 and first- and second-generation Hoveyda-Grubbs catalysts 4 and 5, respectively, as well as the pyridine-tethered Ru carbene catalyst 6. Direct ESI-MS analyses of Ru catalysts 2-6 showed the corresponding radical cations 2?+- 6?+ and the protonated ligand PCy3 and H 2IMes, respectively. Alkali metal adduct ions 2?M+ and 3?M+ (M = Li, Na, K, Cs) and 4?M+- 6?M+ (M = Li, K) could be easily obtained by mixing the CH 2Cl2 solution of catalysts 2-6 with the CH3OH solution of alkali-metal chloride using an online microreactor coupled directly to the electrospray ion source of a quadrupole time-of-flight (Q-TOF) mass spectrometer and were studied by collision-induced dissociation (CID). Remarkably, the alkali metal cationized 14-electron Ru complexes 2a?M + and 3a?M+ formed by dissociation of phosphine from 2 and 3, respectively, were detected directly from solution. The ratio [2a?M+]/[2?M+] increased with decreasing Lewis acidity of M+ from Li+ to Cs+. Moreover, theoretical computations were performed on Ru complexes 2, 5, and 6, showing good agreement with experimental X-ray diffraction data and providing more structural information about the alkali metal adduct ions 2?M+, 5?M+, and 6?M+ (M = Li, K) as well as about the 14-electron species 2a, 5a, and 6a and the respective alkali metal adduct ions.

The Diels-Alder reaction of tribenzohexadehydro[12]annulene (12) and 3,4-diphenyl-2,5-dimethylcyclopentadienone (13) at 300 C gave the triple adduct 2,3,10,11,18,19-hexaphenyl-1,4,9,12,-17,20-hexamethylhexa-o-phenylene (6b) in 13% yield. NMR and X-ray analysis indicated that 6b adopts a screw conformation (C2) rather than a crown conformation (C3), and computational studies seem to rule out any interconversion of the two. Palladium-catalyzed coupling of 1,2-bis(4-bromophenyl)-3,4,5,6- tetraphenylbenzene (17) and the corresponding bis(boronic acid) 18 gave a mixture of linear and cyclic oligomers of hexaphenylbenzene containing two to six hexaphenylbenzene subunits. A macrocyclic tetramer was isolated from this mixture in 5% yield, and X-ray analysis showed it to be the ” supertetraphenylene” 7 (C168H112) that contains a large central cavity and packs to form highly solvated, porous crystals. The difficulties encountered in the purification of 7 led to the development of alternative, more highly selective syntheses that give the pure macrocycle more easily but in essentially the same overall yield.
