PROCESS FOR THE PREPARATION OF 1-OCTENE

Process in two steps for the preparation of 1-octene starting from butadiene which comprises: a first step (a) in which the bis-hydrodimerization of butadiene to 1,7-octadiene is effected in the presence of a catalyst based on a palladium complex containing one or more tri-substituted monodentate phosphines, in an aprotic polar solvent optionally containing an organic base; a second step (b) in which the partial catalytic hydrogenation of 1,7-octadiene to 1-octene is effected, the above process being characterized in that: (i) in the first step the aprotic polar solvent is selected from disubstituted cyclic ureas; (ii) in the second step the catalyst is selected from non? supported ruthenium complexes having general formula (I I): RuXmLn (I I).

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.

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.

Switching and extension of a [c2]daisy-chain dimer polymer

(Chemical Equation Presented) We report the synthesis of a [c2]daisy-chain dimer via ruthenium-catalyzed ring-closing olefin metathesis. Confirmation of the interlocked nature of the structure was achieved through single-crystal X-ray diffraction analysis. The dimer could be readily switched from the bound to the unbound conformation by treatment with 3.0 equiv of KOH and subsequently reprotonated by treatment with 3.0 equiv of HPF6. Azide functionalization of the dimer enabled incorporation in linear step-growth polymer chains using the alkyne-azide “click” reaction. Gel permeation chromatography coupled with multiangle laser light scattering analysis showed the polymers contained 22 dimers and had a radius of gyration of 14.8 nm. Acylation of the amines of the dimers sterically forced elongation of the interlocked units, and MALLS analysis of the polymer showed a 48% increase in the Rg (21.4 nm).

Preparation and redox studies of alpha1- and alpha2-isomers of mono-Ru-substituted dawson-type phosphotungstates with a DMSO Ligand: [alpha1/alpha2-P 2W17O61RuII(DMSO)]8-

Both alpha1- and alpha2-isomers of mono-Ru-substituted Dawson-type heteropolytungstates with a DMSO ligand, [alpha1-P2W17O61Ru II(DMSO)]8- and [alpha2-P2W 17O61RuII(DMSO)]8-, are prepared from the alpha2-isomer of a monolacunary derivative, [alpha2-P2W17O61]10-. Reaction of [alpha2-P2W17O61] 10- with Ru(DMSO)4Cl2 under hydrothermal conditions produces [alpha2-P2W17O 61RuII(DMSO)]8- as a main product together with [alpha1-P2W17O61Ru II(DMSO)]8-, [PW11O39Ru II(DMSO)]5-, and [P2W18O 62]6- as byproducts. By addition of KCl to the reaction mixture, K8[alpha2-P2W17O 61RuII(DMSO)] is isolated in a moderate yield. On the other hand, reaction of [alpha2-P2W17O 61]10- with Ru2(benzene)2Cl 4 under hydrothermal conditions produces an isomeric mixture of [P2W17O61RuIII(H2O)] 7- (alpha1-isomer/alpha2-isomer ratio: ca. 8/1) as a main product together with [PW11O39Ru III(H2O)]4- and [P2W 18O62]6- as byproducts. By addition of acetone to the reaction mixture, K7[P2W17O 61RuIII(H2O)] is isolated in a good yield. Reaction of [P2W17O61RuIII(H 2O)]7- with DMSO produces [alpha1-P 2W17O61RuIII(DMSO)]7- as a main product and [alpha2-P2W17O 61RuIII(DMSO)]7- as a minor product. By addition of KCl and acetone, the alpha1-isomer K 8[alpha1-P2W17O 61RuII(DMSO)] is isolated in a good yield. Both compounds are fully analyzed by CV, NMR (1H, 13C, 31P, and 183W), IR, UV-vis, elemental analysis, mass spectroscopy, and single-crystal structure analysis. Assuming that isomerization does not occur during the reaction of [P2W17O61Ru III(H2O)]7- with DMSO, the isolated [P 2W17O61RuIII(H2O)] 7- contains the alpha1-isomer as a main compound with the alpha2-isomer as a minor compound. Unusual transformation of the alpha2-isomer of [P2W17O 61]10- to the alpha1-isomer occurs. Redox behaviors of [alpha1-P2W17O 61RuII(DMSO)]8- and [alpha2-P 2W17O61RuII(DMSO)]8- are compared together with Ru(DMSO)-substituted alpha-Keggin-type heteropolytungstates, [alpha-XW11O39Ru(DMSO)] n- (X = Si, Ge, and P).
