Highly selective metathesis of 1-octene in ionic liquids

The self-metathesis of 1-octene to form 7-tetradecene catalyzed by ruthenium carbene complexes at low concentrations (0.02 mol %) was investigated in ionic liquids as reaction media and as additives. The study showed that the ionic liquid has a significant effect on the selectivity of the metathesis of 1-octene, with conversion to product of greater than 95% being obtained and selectivities of over 98% being realized. The outcomes of the reactions compared well with those performed under solventless conditions, showing improved conversions and selectivittes.

Activation of grubbs-hoveyda second-generation catalysts employing aromatic ligands bearing a widespread aryl substituent

In this study, an activation strategy for Grubbs-Hoveyda second-generation-type catalysts by utilizing the intramolecular steric strain on the ligands is described. The variant, which is expected to exhibit intramolecular steric strain, containing extensively spread aromatic and alkoxy groups in the ligand structure was prepared and examined. The combination of tricyclic anthracenyl and isopropoxy groups are observed to exhibit the highest catalytic activity among these synthetic catalysts. The activated catalyst was successfully used in a ring-closing metathesis reaction depicting a catalyst loading of the order of 20 mol ppm in dry benzene. The X-ray crystallographic analysis suggests the existence of an intramolecular CH/pi interaction between the sp2 carbon of the anthracenyl group and the methyne hydrogen of the isopropoxy group.

Synthesis of tsetse fly attractants from a cashew nut shell extract by isomerising metathesis

Starting from a purified cashew nut shell extract containing mostly anacardic acid derivatives, the tsetse fly attractants 3-ethyl- and 3-propylphenol were selectively synthesised. The mixture was first converted into 3-(non-8-enyl)phenol in 98% purity via ethenolysis and distillation with concomitant decarboxylation. The olefinic side chain was then shortened by isomerising cross-metathesis with short-chain olefins in the presence of a [Pd(mu-Br)(tBu3P)]2 isomerisation catalyst and a second-generation Hoveyda-Grubbs catalyst, and the synthesis was completed by a hydrogenation step.

Acrylates via Metathesis of Crotonates

Crotonic acid has the potential to be produced from renewable resources at low cost but currently has a limited market. We are investigating catalytic routes to exploit the functionalities of crotonic acid to produce a range of established industrial chemicals. Here we report our work on converting crotonates to acrylates, where a cost-competitive bio-based alternative can provide a market advantage. Our optimized reaction conditions for the cross-metathesis between crotonates and ethylene resulted in an increase in catalyst turnover numbers by 2 orders of magnitude compared with literature values. Control experiments showed the cross-metathesis with ethylene to be an equilibrium reaction. The turnover-number-limiting factor was found to be the stability of the metathesis catalyst.

Enantioselective Construction of Functionalized Cyclopentanes by a Relay Ring-Closing Metathesis and Chiral Amine (Thio)urea-Promoted Michael Addition

A relay strategy is described that permits ring-closing metathesis and bifunctional chiral amine (thio)urea-catalyzed Michael addition reactions to proceed in a one-pot fashion. The process offers an alternative approach to the synthesis of structurally diverse chiral cyclopentanes in good yields and good enantioselectivities.

Synthesis, characterization, and reactivity of complex tricyclic oxonium ions, proposed intermediates in natural product biosynthesis

Reactive intermediates frequently play significant roles in the biosynthesis of numerous classes of natural products although the direct observation of these biosynthetically relevant species is rare. We present here direct evidence for the existence of complex, thermally unstable, tricyclic oxonium ions that have been postulated as key reactive intermediates in the biosynthesis of numerous halogenated natural products from Laurencia species. Evidence for their existence comes from full characterization of these oxonium ions by low-temperature NMR spectroscopy supported by density functional theory (DFT) calculations, coupled with the direct generation of 10 natural products on exposure of the oxonium ions to various nucleophiles.

Bis-mixed-carbene ruthenium-thiolate-alkylidene complexes: Synthesis and olefin metathesis activity

A series of bis-carbene Ru-hydride species, including (IMes)(Im(OMe)2)(PPh3)RuHCl (1) and (SIMes)(Me2Im(OMe)2)(PPh3)RuHCl (2) were prepared and subsequently shown to react with aryl-vinyl-sulfides to give the bis-carbene-alkylidene complexes: Im(OMe)2(SIMes)RuCl(SR)(CHCH3) (R = p-FC6H4 (3), p-(NO2)C6H4 (4)), Im(OMe)2(IMes)RuCl(CHCH3)(SPh) (5), Me2Im(OMe)2(SIMes)RuCl(CHCH3)(SPh) (6), Im(OMe)2(SIMes)(F5C6S)RuCl(CHR) (R = C4H9 (9), C5H11 (10)). The activity of these species in the standard Grubbs’ tests for ring-opening metathesis polymerization, ring-closing and cross-metathesis are reported. Although these thiolate derivatives are shown to exhibit modest metathesis activities, the reactivity is enhanced in the presence of BCl3. This journal is

Synthesis of 6-Hydroxysphingosine and alpha-Hydroxy Ceramide Using a Cross-Metathesis Strategy

(Chemical Equation Presented) In this paper, a new synthetic route toward 6-hydroxysphingosine and alpha-hydroxy ceramide is described. The synthesis employs a cross-metathesis to unite a sphingosine head allylic alcohol with a long-chain fatty acid alkene that also bears an allylic alcohol group. To allow for a productive CM coupling, the sphingosine head allylic alcohol was protected with a cyclic carbonate moiety and a reactive CM catalyst system, consisting of Grubbs II catalyst and CuI, was employed.

Metathesis and metallotropy: A versatile combination for the synthesis of oligoenynes

We have demonstrated that the combined use of enyne metathesis and metallotropic [1,3]-shift of the corresponding alkynyl ruthenium carbenes is a powerful synthetic tool to construct oligoenynes. In this reaction, alkynyl carbene intermediates formed from an initial ring-closing metathesis reaction (RCM) undergo repetitive [1,3]-shifts and RCMs to give the final products. Linear poly-1,3-diynes containing repeating functionality of the type -[XCH2CCCCCH2]n- generated long-chain conjugated oligoenynes up to n = 5. Copyright

Asymmetric total synthesis and X-ray crystal structure of the cytotoxic marine diterpene (+)-vigulariol

(Figure Presented) A crystal from the China sea: The asymmetric total synthesis of (+)-vigulariol (see picture: red O, blue C, white H) has been accomplished in eight linear steps starting from (R)-cryptone, which is readily available from eucalyptus oil. Key steps involve an asymmetric homoaldol reaction of chiral allyl carbamates and THF cyclocondensation. Ring-closing metathesis led to the tricyclic framework of the cladiellin diterpenes.
