Nonmetathetic activity of ruthenium alkylidene complexes: 1,4-hydrovinylative cyclization of multiynes with ethylene

An efficient 1,4-hydrovinylative cyclization reaction of triynes and tetraynes catalyzed by ruthenium alkylidene complexes under ethylene is described. The regioselectivity of vinyl group incorporation can be controlled by the nature of the substituent on the alkyne, and the Grubbs second-generation catalyst is the most effective among typical ruthenium alkylidene complexes.

Synthesis of enantioenriched gamma-quaternary cycloheptenones using a combined allylic alkylation/Stork-Danheiser approach: Preparation of mono-, bi-, and tricyclic systems

A general method for the synthesis of beta-substituted and unsubstituted cycloheptenones bearing enantioenriched all-carbon gamma-quaternary stereocenters is reported. Hydride or organometallic addition to a seven-membered ring vinylogous ester followed by finely tuned quenching parameters achieves elimination to the corresponding cycloheptenone. The resulting enones are elaborated to bi- and tricyclic compounds with potential for the preparation of non-natural analogs and whose structures are embedded in a number of cycloheptanoid natural products.

Synthesis and catalytic activity of ruthenium complexes modified with chiral racemic per- and polyfluorooxaalkanoates

Silver salts of racemic 2H-perfluoro(3-oxahexanoic) (3a), perfluoro(2-methyl-3-oxahexanoic) (3b) and 2,3,3,3-tetrafluoro-2-methoxypropanoic acid (3c) gave with Hoveyda-Grubbs 2nd generation catalyst 4 or its bis(polyfluoroalkylated) analogue 5 the corresponding bis(polyfluoroacylated) ruthenium complexes 1a?1c or 2a, 2b as mixtures of three diastereoisomers. Their catalytic activity in model ring-closing metathesis (RCM) reactions decreased in the order 1b?2b?>?1a?2a?>?1c due to increased steric hindrance around the catalytic centre in complexes 1a, 1c and 2a, as well as due to lower acidity of acid 3c resulting in lower electrophilicity of the complex 1c. Thus, the complexes 1b and 2b displayed high activity in RCM of bis-unsaturated malonates forming disubstituted (RCM2) or trisubstituted (RCM3) double bond and were even significantly active in the formation of tetrasubstituted bond (RCM4), while complexes 1a, 1c were active in RCM2 but inactive in RCM3. Moreover, the yield of RCM2 catalyzed with complex 1c was rather low.

Synthesis and properties of fluorescent dyes conjugated to hyperbranched polyglycerols

Convergent syntheses of polyglycerol hyperbranched polymers containing fluorescent labels (fluorescein or perylene diimide (PDI)) at their core are presented. The hyperbranched polyglycerol (HPG) precursors were synthesized using a one step polymerization reaction wherein the initiator leaves a single reactive group for dye functionalization. For further site isolation, allylated HPG was synthesized allowing cross-linking via ring closing metathesis and subsequent dihydroxylation to produce water-soluble, fluorescent nanoparticles. The dyes produced showed improvements in photostability, water solubility, or quantum yield, depending on both the dye used and cross-linking. These fluorescent nanoparticles outperformed similar dyes that incorporated linear polyethylene glycol (PEG) polymers.

Two-photon spectroscopy of tungsten(0) arylisocyanides using nanosecond-pulsed excitation

The two-photon absorption (TPA) cross sections (delta) for tungsten(0) arylisocyanides (W(CNAr)6) were determined in the 800-1000 nm region using two-photon luminescence (TPL) spectroscopy. The complexes have high TPA cross sections, in the range 1000-2000 GM at 811.8 nm. In comparison, the cross section at 811.8 nm for tris-(2,2?-bipyridine)ruthenium(ii), [Ru(bpy)3]2+, is 7 GM. All measurements were performed using a nanosecond-pulsed laser system.

Simultaneous production of biobased styrene and acrylates using ethenolysis

Phenylalanine (1), which could be potentially obtained from biofuel waste streams, is a precursor of cinnamic acid (2) that can be converted into two bulk chemicals, styrene (3) and acrylic acid (4), via an atom efficient pathway. With 5 mol% of Hoveyda-Grubbs 2nd generation catalyst, 1 bar of ethylene, and using dichloromethane as solvent, cinnamic acid (2) can be converted to acrylic acid and styrene at 40 C in 24 h with 13% conversion and 100% selectivity. Similar results are obtained using cinnamic acid esters (methyl, ethyl and n-butyl) as substrates and optimisation leads to higher conversions (up to 38%). For the first time, cross-metathesis of these types of electron deficient substrates was achieved.

An ionic liquid-supported ruthenium carbene complex: A robust and recyclable catalyst for ring-closing olefin metathesis in ionic liquids

The synthesis of an ionic liquid-supported olefin metathesis catalyst derived from Grubb’s ruthenium carbene complex is described. This new supported catalyst has been used in BMI¡¤PF6 solvent, and this allowed success in solving the challenging problem of catalyst recycling. The IL catalyst in BMI¡¤PF6 can be recovered and reused up to 10 consecutive cycles in RCM reactions of several dienes with excellent conversions. Moreover, the IL catalyst shows a remarkable stability in BMI¡¤PF6 and can be stored several months without loss of activity. These results clearly demonstrate the importance of anchoring an imidazolium ionic liquid pattern to the catalyst to avoid its leaching from the BMI¡¤PF6 phase. Copyright

Anionic ligand exchange in Hoveyda-Grubbs ruthenium(II) benzylidenes

A series of Hoveyda-Grubbs benzylidenes, Ru(X)2-(IMesH 2)(=CH-2-(2-PrO)C6H4) (X = Cl, Br, CF 3CO2, C2F5-CO2; IMesH2 = 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene) were demonstrated to undergo intermolecular anionic ligand exchange when mixed. The implication is that anionic ligand exchange is occurring between identical ruthenium benzylidenes at all times in solution. A mechanism involving bridged dimers is invoked.

Synthesis of Functionalized 6,5- and 7,5-Azabicycloalkane Amino Acids by Metathesis Reactions

Azabicyclo[4.3.0]- and [5.3.0]alkanone amino acid derivatives were easily prepared by submitting the same starting dipeptide to a direct ring-closing enyne metathesis or an ethylene-mediated cross-enyne metathesis/ring-closing metathesis, respectively. The reactivity of the newly synthesized 6,5- and 7,5-fused bicyclic scaffolds was then investigated to obtain variously functionalized derivatives with potential applications in the field of peptides/peptidomimetics.
