Four new cyclopentadienylruthenium(II)-acetophenone-4(N)-substituted thiosemi-carbazone complexes, with the general formula [Ru(?5-C5H5)(H-Aptsc)PPh3].Cl (1), [Ru(?5-C5H5)(H-Apmtsc)PPh3].Cl (2), [Ru(?5-C5H5)(H-Ap-etsc)PPh3].Cl (3) and [Ru(?5-C5H5)(H-Ap-ptsc)PPh3].Cl (4) were synthesised and characterised (1H NMR, 13C NMR, IR and electronic spectroscopy). The molecular structure of representative complexes 2 and 3 was confirmed by single crystal X-Ray diffraction technique. The binding ability of complexes (1?4) to calf-thymus DNA (CT DNA) and Bovine Serum Albumin (BSA) has been explored by absorption and emission titration methods. Based on the observations, an electrostatic and an intercalative binding mode have been proposed for the complexes with CT-DNA. The BSA protein binding studies have been monitored by quenching of tryptophan and tyrosine residues in the presence of complexes and static type of quenching mechanism has been proposed. In vitro free radical scavenging activity was performed by DPPH radical. The complexes (1?4) exhibited highest scavenging activity than conventional standard vitamin C (IC50 = 5.65 ± 0.12). Further, antibacterial activity of the complexes has been screened against four pathogenic bacteria such as Salmonella paratyphi, Staphylococcus aureus, Escherichia coli and Bacillus subtilis. From the results it is found that all the complexes exhibited significant activity against the pathogens and among them, complex 3 exhibited higher activity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C41H35ClP2Ru, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 32993-05-8, in my other articles.

Meayamycin B is currently the most potent modulator of the splicing factor 3b subunit 1 and used by dozens of research groups. However, current supply for this natural product analogue is limited because of the lengthy synthetic scheme. Here, we report a more concise, more cost-effective, and greener synthesis of this compound by developing and employing a novel asymmetric reduction of a prochiral enone to afford an allylic alcohol with high enantioselectivity. In addition to this reaction, this synthesis highlights a scalable Mukaiyama aldol reaction, Nicolaou-type epoxide opening reaction, stereoselective Corey-Chaykovsky-type reaction, and a modified Horner-Wadsworth-Emmons Z-selective olefination. We also discuss a Z-E isomerization during the alpha,beta-unsaturated amide formation. The new synthesis of meayamycin B consists of 11 steps in the longest linear sequence and 24 total steps.

A family of chiral diphosphanes with systematically tunable electronic and steric properties have been used in the asymmetric hydrogenation of beta-aryl ketoesters with excellent ee values (up to 99.8%) by taking advantage of remarkable 4,4?-substituent effects on binap. These highly enantioselective Ru catalysts have also been effectively immobilized in room-temperature ionic liquids (RTIL).

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a Article，once mentioned of 246047-72-3, Formula: C46H65Cl2N2PRu

The synthesis and characterization of monomeric and dendritic Grubbs II and Hoveyda-Grubbs II-based complexes are reported. These complexes were synthesized via a route based on the connection of monomeric or dendritic N-alkyl-N?-mesitylimidazol-2-ylidene pre-ligands to Grubbs I or Hoveyda-Grubbs I complexes. The immobilization of a modified Grubbs II type catalyst on a G0 carbosilane dendrimer was successfully carried out. Together with monomeric Grubbs II and Hoveyda-Grubbs-analogs and several commercially available olefin metathesis catalysts, the soluble, homogeneous G0-dendritic Grubbs II complex was tested as catalyst in the ring closing metathesis of diethyl diallylmalonate. The immobilized complex proved to outperform its monomeric analog in this reaction at room temperature, whereas it was found to be slightly slower at reflux temperature.

Both (3R,5S)- and (3R,5R)-gingerdiols were synthesized. Their 1,3-diol motifs were derived from enantiopure epoxy chiral building blocks that were readily accessible from D-gluconolactone. The effect of deuterating the OH groups of the natural isomer on its optical rotation was also examined. In the course of the syntheses of the targets, an unexplored cross-metathesis (CM) reaction of unprotected 5-substituted pent-1-ene-3,5-diols was investigated, in which the CM product readily underwent an allylic epimerization and oxidation, as the starting diols rearranged into ketones with unprecedented ease. These problems were eventually resolved by performing the CM reaction in toluene in the presence of phenol. The cause of these unexpected, yet very interesting phenomena, was determined to be the presence of the unprotected OH group at C-5 of the 5-substituted pent-1-ene-3,5-diol. A mechanistic rationale is also presented. Copyright
