Tandem isomerisation-metathesis catalytic processes of linear olefins in ionic liquid biphasic system

trans-3-Hexene is converted to heavier linear olefins by a tandem Ru-catalysed biphasic isomerisation/metathesis sequence. The difference in olefin metathesis and isomerisation rates is modulated by keeping the ionophilic metathesis catalyst in an ionic phase whilst the isomerisation catalyst is in another organic non-polar phase.

Selective linear coupling reaction of acetylene and acrylonitrile catalyzed by the well-defined metallacyclopentadiene complex C5Me5(PPh3)(Cl)RuCH=CHCH=CH

The metallacyclopentadiene complex C5Me5(PPh3)(Cl)RuCH=CHCH=CH (1) was found to catalyze the linear coupling reaction of acetylene and acrylonitrile to give predominantly 2(E),4(Z),6-heptatrienenitrile (3; TON = 15, 85% selectivity). The coupling reaction is proposed to occur via an initial PPh3 dissociation from 1 and the subsequent insertion of acrylonitrile.

Click chemistry approach for the regioselective synthesis of iso-indoline-1,3-dione-linked 1,4 and 1,5 coumarinyl 1,2,3-triazoles and their photophysical properties

Copper-catalyzed reaction of N-propargyl isoindoline-1,3-dione and 4-azidomethyl coumarins / 4-azidomethyl-1-aza coumarins under click chemistry conditions afforded 1,4-disubstituted 1,2,3-triazoles, whereas ruthenium catalysis yielded isomeric 1,5-disubstituted 1,2,3-triazoles. The two regioisomers have been distinguished by NOE studies. UV absorption for a given pair of isomers exhibited similar trend, whereas fluorescence measurements showed considerable differences. Photo physical studies on the interaction of azides with copper and ruthenium have also been performed.

Pyramidal stability of 16-electron half-sandwich intermediates [CpRu(P-P)]+ with P-P ligands forming four- to six-membered chelate rings

This paper reports the synthesis, isomer separation, and X-ray characterization of the compounds (SRu,Sc)-/(RRU,Sc)- [CpRu(Chairphos)Cl], Chairphos = (S)-1,3-bis(diphenylphosphanyl)butane, and cis-/trans-[CpRu(Dppm-Me)Cl], Dppm-Me = 1,1-bis(diphenylphosphanyl)etnane. The Cl/I exchange reactions proceeded with predominant retention of the metal configuration, accompanied by some inversion, except for rrai-[CpRu(Dppm- Me)Cl], which was stereospecifically converted to trans-[CpRu(Dppm-Me)I]. Temperature-dependent kinetic measurements afforded rates and activation parameters of the Cl/I exchange and epimerization reactions that follow basilica-type energy profiles. Dissociation of CF from [CpRu(Chairphos)Cl] and [CpRu(Dppm-Me)Cl] gives pyramidal intermediates [CpRu(Chairphos)]+ and [CpRu(Dppm-Me)]+, which maintain the metal configuration. The 16-electron intermediates can react with excess I- to form the iodo complexes with retention of the metal configuration, or they can change the metal configuration by pyramidal inversion, leading to formation of iodo complexes with inverted metal configuration. The kinetic measurements show that the pyramidal inversion via planar transition states depends on the P-Ru-P’ angles. It increases with decreasing chelate ring size, because small P-Ru-P’ angles resist planarization in the transition, which requires larger P-Ru-P’ angles.

Benzimidazoles as ligands in the ruthenium-catalyzed enantioselective bifunctional hydrogenation of ketones

A series of Cl2Ru(diphosphane)L2 (II) complexes in which L = N1-alkylated benzimidazoles, bonding to the metal through nitrogen, have been synthesized and characterized. In the case of 1-methylbenzimidazole, the resulting complexes exist as statistical mixtures of all possible conformational isomers. When the size of the substituent on the benzimidazole was increased to complexes could be prepared that exist as a single diastereomer. All complexes possessing benzimidazole ligands bound to the ruthenium center are active for the mild and chemoselective hydrogenation of ketones in the presence of alkenes. Catalysts that exist as a single diastereomer, prepared with enantiomerically pure diphosphanes, catalyze the hydrogenation of prochiral ketones with moderate levels of enantioselectivity that are significantly improved relative to catalysts existing in several conformations.

Iridium-catalyzed enantioselective allylic substitution of unstabilized enolates derived from alpha,beta-unsaturated ketones

We report Ir-catalyzed, enantioselective allylic substitution reactions of unstabilized silyl enolates derived from alpha,beta-unsaturated ketones. Asymmetric allylic substitution of a variety of allylic carbonates with silyl enolates gave allylated products in 62-94% yield with 90-98% ee and >20:1 branched-to-linear selectivity. The synthetic utility of this method was illustrated by the short synthesis of an anticancer agent, TEI-9826.

A Convergent Synthetic Strategy towards Oligosaccharides containing 2,3,6-Trideoxypyranoglycosides

A de novo synthetic strategy for the production of oligosaccharides containing 2,3,6-trideoxypyranoglycoside is reported. The key event is the Pd-catalyzed asymmetric diastereoselective hydroalkoxylation of ene-alkoxyallene-linked glycosidic fragments. The utility of this approach was demonstrated by the activation-free, stereodivergent, and convergent synthesis of various 2-deoxyoligosaccharides, as well as their aglycon conjugates.

Poly(alkylidenimine) dendrimers functionalized with the organometallicmoiety [Ru(nu 5-C5H5)(PPh3)2]+ as promising drugs against cisplatin-resistant cancer cells and humanmesenchymal stem cells

Here and for the first time, we show that the organometallic compound [Ru(nu5-C5H5)(PPh3)2Cl] (RuCp) has potential to be used as a metallodrug in anticancer therapy, and further present a new approach for the cellular delivery of the [Ru(nu5-C5H5)(PPh3)2]+ fragment via coordination on the periphery of low-generation poly(alkylidenimine) dendrimers through nitrile terminal groups. Importantly, both the RuCp and the dendrimers functionalized with [Ru(nu5-C5H5)(PPh3)2]+ fragments present remarkable toxicity towards a wide set of cancer cells (Caco-2, MCF-7, CAL-72, and A2780 cells), including cisplatin-resistant human ovarian carcinoma cell lines (A2780cisR cells). Also, RuCp and the prepared metallodendrimers are active against human mesenchymal stem cells (hMSCs), which are often found in the tumor microenvironment where they seem to play a role in tumor progression and drug resistance.

Methylated cyclodextrins: An efficient protective agent in water for zerovalent ruthenium nanoparticles and a supramolecular shuttle in alkene and arene hydrogenation reactions

Zerovalent ruthenium(0) nanoparticles in the size range of 2.5 nm were easily prepared by chemical reduction of ruthenium salt with an excess amount of sodium borohydride and were efficiently stabilized by methylated cyclodextrins. The optimization of the catalytic system has been carried out in terms of stability and catalytic activity, considering the hydrogenation of olefinic compounds under biphasic liquid-liquid conditions. Efficient and controlled chemoselectivities were obtained in the hydrogenation of arene derivatives by the relevant choice of cavity and methylation degree of the cyclodextrins. Finally, the hydrogenation of alpha- and beta-pinenes leads to the major formation of cis-pinanes, interesting synthons for fine chemistry, with high diastereoisomeric excesses.
