A stereoselective route for the total synthesis of anticancer marine natural product (+)-varitriol (1) is detailed herein. The impressive biological activity and interesting structural features of natural (+)-varitriol fuelled us to undertake the synthesis of some higher analogues (1a-j) of this molecule. The key features of the synthetic strategy include one-pot Wittig olefination followed by a highly diastereoselective oxa-Michael addition to assemble stereochemically pure tetrasubstituted THF moiety of the natural varitriol and olefin cross metathesis to couple the aromatic part with tetrasubstituted THF moiety. The total synthesis of title natural product is efficient with 21.8% overall yield for 9 linear steps from d-ribose and thus facilitates the more scaled-up practical route for the synthesis of 1 and its analogues as well. The synthetic (+)-varitriol (1) and its analogues were screened for their cytotoxicity. The present synthetic approach paves the way for preparation of numerous analogues of the title natural product for drug development.

Some scientific research about Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II)

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 32993-05-8, help many people in the next few years., Application of 32993-05-8

Synthetic Route of 32993-05-8, An article , which mentions 32993-05-8, molecular formula is C41H35ClP2Ru. The compound – Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II) played an important role in people’s production and life.

The complex [CpRu(eta6-naphthalene)]PF6 (2) is a readily accessible and air-stable source of the CpRu+ fragment (Cp = eta5C5H5) for applications in complex synthesis and catalysis. The utility of this precursor complex is demonstrated in a number of experiments: The counterion of 2 is exchanged by reaction with cinchonidinium A-TRISPHAT to give [CpRu(eta6-naphthalene)]A- TRISPHAT (4; with X-ray crystal structure). Ligand exchange of 2 in acetonitrile with (Z,Z)- 1,5-cyclooctadiene (COD) produces [CpRu(eta2: eta2-COD)(MeCN)]PF6 (5; with X-ray crystal structure); with chelating phosphanes (P-P), complexes [CpRu(P-P)(MeCN)]PF6 are selectively generated, and starting with a 1,4-diazadiene, a solvento complex [CpRu(diazadiene-N,N?)(MeCN)]PF6 is obtained. Stepwise reaction of 2 (or 4) in acetonitrile with different monodentate phosphanes PR3 and PR’3 first gives [CpRu(PR 3)(MeCN)2]+ (I), then the chiral-at-metal cation [CpRu(PR3)(PR’3)(MeCN)]+ (II), which was resolved spectroscopically (31P NMR) when combined with the enantiopure Delta-TRISPHAT counterion. Complex cations of type I or II incorporating 2-diphenylphosphinopyridines as ligands display either the eta1-p or the chelating eta2-P,N coordination mode, depending on the size of the ligand and, in solution, the solvent. Reaction of 2 with 3 equiv of triarylphosphanes (PR3) in hot acetone gives rise to [CpRu(PR3)3]+, including the previously unknown cation [CpRu(PPh3)3]+. The in situ combination of 2 and 2 equiv of bulky 6-substituted 2-pyridylphosphanes catalyzes the anti-Markovnikov hydration of terminal alkynes to aldehydes. Either complex 2 or 5 catalyzes the [2+2+2]-cycloaddition of COD with alkynes. Complex 5 is a catalyst for the coupling of allyl alcohols with terminal alkynes to give 4-alkenones.

In the last decade a number of reports have been published on the synthesis and characterization of bridged cyclodextrin dimers (bis-CDs) connected with linkers of different lengths and structures. These dimers, having two hydrophobic cavities in close proximity, display much higher binding affinities and molecular selectivities than parent CDs, forming stable supramolecular adducts. We describe new synthetic protocols for the preparation of bis(beta-CDs) bearing 2-2?, 3-3? and 6-6? bridges. Some of the critical steps were carried out either under high-intensity ultrasound (US) or microwave (MW) irradiation. Bis(beta-CDs) containing 6-6? ureido- and thioureido-bridges were prepared in high yields by a MW-promoted aza-Wittig reaction using polymer-bound triphenylphosphine, while those containing 2,2? and 3,3? bridges were prepared from mono-alkenyl beta-CDs by the cross-metathesis reaction (homodimerization) in the presence of 2 nd-generation Grubbs catalyst under sonochemical conditions. By these improved protocols CD dimers could be obtained in gram amounts to prepare stable adducts of bis-CDs with contrast agents (CAs) containing gadolinium(iii) chelates. In the case of Gd(iii) chleate “G-1” the inclusion complexes were found to be 2 to 3 orders of magnitude more stable than that formed by beta-CD (Kass = 4.3 × 104 M-1 vs 8.0 × 102 M-1). Relaxivity increased as well by factors of 3 and 4, viz. from 9.1 mM-1 s-1 (beta-CD) to 27.7 and 35 mM-1 s-1. The Royal Society of Chemistry 2006.

The three-dimensional orientation monitoring of anisotropic nanoparticles during dynamic processes is a fundamental issue. Herein we show that incorporation of a single fluorescent reporter molecule is a promising concept toward this goal. As a model system, shape anisotropic single lamella polyethylene (PE) nanocrystals bearing one single fluorescent reporter molecule were prepared via ring-opening metathesis polymerization (ROMP) of highly ring-strained trans-cyclooctene (trCOE) using a mixture of a dye-functionalized ruthenium-based initiator (1; perylene diimide (PDI) substituted Hoveyda-Grubbs second generation Ru alkylidene) and an appropriate excess of the unlabeled analogue (2; Hoveyda-Grubbs second generation Ru alkylidene) in aqueous microemulsion as a key step and subsequent exhaustive hydrogenation (>99.9%) of the main-chain unsaturated polymer in the nanoparticles to yield nanocrystals of high molecular weight, strictly linear PE (Mn = 8 × 105 g mol-1; M w/Mn = 1.4). TEM and AFM show a particle thickness of ca. 12 nm with a lateral extension of typically 45 nm. Comparable initiation kinetics of both complexes 1 and 2, which is a key requirement for this approach, were revealed by fluorescence spectroscopy studies (DeltaH ? = 57.4 kJ mol-1, DeltaS? = -73.0 J mol-1 K-1 for 1 vs DeltaH? = 63.6 kJ mol-1, DeltaS? = -80.8 J mol-1 K-1 for 2 for the initiation with n-butyl vinyl ether, respectively). The labeled nanocrystals were characterized by means of single molecule fluorescence spectroscopy. Orientational analysis via defocused wide-field fluorescence microscopy (DWFM) revealed a fixed orientation of the chromophores within the nanocrystals, with their long molecular axis predominantly oriented parallel to the polar axis of the nanoparticles.

Disclosed is a process for production of an asymmetric binuclear metal complex represented by the general formula: (L1)2M1(BL)M2(L2)2(X)n wherein M1 and M2, which may be the same as or different from each other, represent a transition metal; L1 and L2, which are different from each other, represent a chelate ligand capable of multidentate coordination and two L1s may be different from each other and two L2s may be different from each other; BL represents a bridging ligand having at least two cyclic structures each containing a hetero atom, the hetero atoms contained in the cyclic structures being ligand atoms coordinating to M1 and M2; X represents a counter ion; and n is the number of counter ions needed to neutralize the charge of the complex. In the process, the binuclear metal complex is isolated by adjusting the pH of the solution containing the binuclear metal complex to a value higher than 2.5. The binuclear metal complex obtained may be used as a dye to produce a photoelectric conversion element and a photochemical battery having higher photoelectric conversion efficiency and higher durability.

The use of the ring-closing enyne metathesis (RCEYM) as a methodology for the synthesis of the azonino[5,4-b]indole system, featuring the tricyclic substructure of the alkaloids cleavamine and quebrachamine, has been explored. Three series of enyne substrates were studied for their compatibility with the RCEYM reaction. In addition to the usual substrates bearing either a terminal or an internal alkyne, for the first time enynes with an alkynyl halide moiety were also considered. Although the metathesis cyclization allowed for assembly of the azoninoindole nucleus in all three series, an effective catalytic cycle was only noted for internal alkyne substrates. On the basis of the experimental results, the “yne-then-ene” pathway seems to be the mechanism at play in these reactions. The use of ring-closing enyne metathesis (RCEYM) as a methodology for the construction of the nine-membered ring of the 2,3,4,7-tetrahydro-1H-azonino[5,4-b]indole system has been explored.
