Ruthenium polypyridine complexes of tris-(2-pyridyl)-1,3,5-triazine – Unusual building blocks for the synthesis of photochemical molecular devices

The mononuclear compounds bis-(2,2?-bipyridine)ruthenium(ii)-(tris(2- pyridyl)triazine) [(bpy)2Ru(tpt)](PF6)21 and bis-(4,4?-di-tert-butyl-2,2?-bipyridine)ruthenium(ii) -(tris(2-pyridyl)triazine) [(tbbpy)2Ru(tpt)](PF6) 22 have been synthesised and fully characterised. The attempted syntheses of heterodinuclear complexes with the tris(2-pyridyl)triazine (tpt) ligand as bridging ligand and various palladium(ii)- and platinum(ii)-dichloro complexes using the ruthenium complexes as starting materials resulted in a partial hydrolysis of the triazine based bridging ligand in case of 2 and an unselective decomposition in case of 1. Compound 2 reacts with Pd(DMSO) 2Cl2 and Pt(DMSO)2Cl2 substituting three ligands from the metal centres of these precursors with partial hydrolysis of the triazine moiety of the bridging ligand yielding the dinuclear complexes bis-(4,4?-di-tert-butyl-2,2?-bipyridine)ruthenium(ii) -N-((picolinamido)(pyridin-2-yl)methylene)picolinamide)chloro-palladium(ii) [(tbbpy)2Ru(tptO)PdCl](PF6)23 and bis-(4,4?-di-tert-butyl-2,2?-bipyridine) ruthenium(ii)-N- ((picolinamido)(pyridin-2-yl)methylene)picolinamide)chloro-platinum(ii) [(tbbpy)2Ru(tptO)PtCl](PF6)24. The newly formed bridging ligand coordinates in a bidentate fashion at the ruthenium centre and acts as a tridentate ligand for the second metal centre. The structures of all the complexes have been fully characterised and their photophysical properties are reported. A similar reaction sequence using the (4?-(p-bromophenyl)-2, 2?:6?,2?-terpyridine)ruthenium(ii)-(tris(2-pyridyl)triazine) complex [(BrPhtpy)Ru(tpt)](PF6)25 and Pd(CH 3CN)2Cl2 as starting materials did not yield the hydrolysed bridging ligand but the expected dinuclear complex [(BrPhtpy)Ru(tpt)PdCl2](PF6)26 suggesting that the coordination of two pyridine rings of the tpt by the ruthenium centre is essential for the stabilisation of the tpt frame work. Preliminary investigations show that the dinuclear ruthenium-palladium and -platinum complexes are not active catalysts in the light-driven hydrogen production. The Royal Society of Chemistry 2009.

Total synthesis of AMF-26, an antitumor agent for inhibition of the golgi system, targeting adp-ribosylation factor 1

An effective method for the total synthesis of 1 (AMF-26), a potentially promising new anticancer drug that disrupts the Golgi system by inhibiting the ADP-ribosylation factor 1 (Arf1) activation, has been developed for the first time. The construction of the chiral linear precursor (a key to the synthesis) was achieved by the asymmetric aldol reaction followed by the computer-assisted predictive stereoselective intramolecular Diels-Alder reaction. The global antitumor activity of the totally synthetic 1 against a variety of human cancer cells was assessed using a panel of 39 human cancer cell lines (JFCR39), and it was shown that the synthetic 1 strongly inhibited the growth of several cancer cell lines at concentrations of less than 0.04 muM. Biological assays of novel derivatives, 26 and 31, which have different side-chains at the C-4 positions in the Delta1,2-octalin backbone, disclosed the importance of the suitable structure of the side-chain containing conjugated multidouble bonds.

Reactions of ruthenium Cp phosphine complex with 4,4-disubstituted-1,6- enynes: Effect of methyl substituents in the olefinic fraction

We studied chemical reactions of Cp(PPh3)2RuCl with nine 1,6-enyne compounds (1-4, 8, 12, 19, 21, and 22) in which the triple bond is associated with propargylic alcohol and the olefinic group has various substituted methyl groups. For the enyne compounds 1-3 with no substituted methyl group, the reaction takes place at the propargylic alcohol first giving the allenylidene complex 6 which could undergo a skeletal rearrangement to yield the disubstituted vinylidene complex 7. By changing the propargylic alcohol to propargylic ether, the reaction gives the carbene complex 10 as the major product and the butadiene complex 9 by a cyclization reaction as the minor product. For enyne 12 with two methyl groups at the terminal carbon of the olefinic part, formation of either of the carbene complexes 15 and 16 with a substituted cyclopentenyl ring at Calpha or the vinylidene complex 17 is controlled by the use of solvent. For the formation of 15 and 16, a C-C bond-forming cyclization reaction is proposed to occur at Cbeta in an intermediate where the triple bond is pi-coordinated. However, for the vinylidene intermediate, the reaction may proceed by the formation of the allenylidene, which undergoes a retro-ene reaction to bring about cleavage of the dimethyl substituted allyl group giving 17. For two enynes 21 and 22 where each olefinic portion is internally substituted with one methyl group, two vinylidene complexes 23 and 24 each with a five-membered ring bonded at Cbeta are isolated. The reaction proceeds via formation of an allenylidene intermediate followed by a cyclization at Cgamma. Stabilization of the cationic charge by the presence of methyl subsituents clearly controls the reaction pathway to give different products. These chemical reactions and their mechanisms are corroborated by structure determinations of five ruthenium complexes using single crystal X-ray diffraction analysis.

Arene?Ruthenium(II) Complexes with Bioactive ortho-Hydroxydibenzoylmethane Ligands: Synthesis, Structure, and Cytotoxicity

The synthesis of a series of neutral arene?ruthenium(II) complexes (arene = p-cymene, hexamethylbenzene, and benzene) [(arene)Ru(HDB)Cl] derived from the reaction of the appropriate arene?ruthenium(II) dimers and ortho-hydroxydibenzoylmethane (HDBH), a potent inhibitor of cell proliferation, is described. In addition, related ionic complexes [(arene)Ru(HDB)(PTA)](SO3CF3) (PTA = 1,3,5-triaza-7-phosphaadamantane) have been prepared. The structure of three complexes has been confirmed by X-ray crystallography. The cytotoxicity of the complexes has been evaluated against human ovarian carcinoma cells (A2780 and A2780cisR), as well as against nontumorigenic human embryonic kidney (HEK293) cells, and compared to the free ligand and cisplatin. Two of the complexes, that is from the first series with p-cymene and hexamethylbenzene, display relevant activities against the cisplatin-resistant A2780cisR cancer cell line.

Ru-Catalyzed Chemo- And Enantioselective Hydrogenation of 2,4-Pentadien-1-ones: Synthesis of Chiral 2,4-Pentadien-1-ols

The asymmetric hydrogenation of 2,4-pentadien-1-ones has been achieved by using trans-RuCl2[(R)-XylylSunPhos][(R)-Daipen] as a catalyst under basic conditions. This hydrogenation demonstrated exclusive C1-carbonyl selectivity, and thus the conjugated 2,4-diene motifs remained untouched, which provides a synthetically useful method for various chiral 2,4-pentadien-1-ols.

SYNGAS REACTIONS-PART XI. THE RUTHENIUM ‘MELT’ CATALYZED OXONATION OF INTERNAL OLEFINS.

The hydroformylation of internal olefin substrates to give predominantly linear ‘oxo’ alcohols is catalyzed by ruthenium carbonyl ‘melt’ catalysts, wherein the ruthenium carbonyls are dispersed in low m. p. quaternary phosphonium salts. The anionic ruthenium cluster, left bracket HRu//3(CO)//1//1 right bracket ** minus , is the predominant metal carbonyl species in the reactant solutions. Improved alcohol linearity can be achieved through addition of certain chelating N- and P-donor ligands, such as 2,2 prime -bipyridyl, as well as by the choice of quaternary phosphonium salt matrix.
