Flexible and enantioselective access to jaspine B and biologically active chain-modified analogues thereof

Whereas the all-cis tetrahydrofuran framework of the cytotoxic anhydrophytosphingosine jaspine B is considered as a relevant pharmacophore, little is known about the influence of the aliphatic chain of this amphiphilic molecule on its activity. We developed a synthetic strategy allowing flexible introduction of various lipophilic fragments in the jaspine’s skeleton. The route was validated with two distinct approaches to jaspine B. Five chain-modified analogues were also prepared. Biological evaluation of these derivatives demonstrated a good correlation between their cytotoxicity and their capacity to inhibit conversion of ceramide into sphingomyelin in melanoma cells. A series of potent and selective inhibitors of sphingomyelin production was thus identified. Furthermore, the good overall potency of an omega-aminated analogue allowed us to dissociate of the pharmacological action of jaspine B from its amphiphilic nature.

Ionic-tagged catalytic systems applied to the ethenolysis of methyl oleate

A novel high selective ionophilic Hoveyda-type complex for the methyl oleate ethenolysis was prepared from Grubbs first generation catalyst. Ethenolysis under classical biphasic systems in ionic liquids showed to be mass-transference limited. This drawback was successfully solved by the catalyst dispersion on high specific surface area inorganic supports through a thin layer of ionic liquids (ILs). The supported ionic liquid phase (SILP) catalyst properties were patterned by the support type, IL cation and support/IL mass ratio. The SILP prepared with the IL 1-isopentyl-3-methylimidazole hexafluorophosphate and silica showed a turnover number higher (up to 2350) than that of biphasic systems (up to 1045).

Galacto-configured aminocyclitol phytoceramides are potent in vivo invariant natural killer T cell stimulators

A new class of alpha-galactosylceramide (alphaGC) nonglycosidic analogues bearing galacto-configured aminocyclitols as sugar surrogates have been obtained. The aminocyclohexane having a hydroxyl substitution pattern similar to an alpha-galactoside is efficiently obtained by a sequence involving Evans aldol reaction and ring-closing metathesis with a Grubbs catalyst to give a key intermediate cyclohexene, which has been converted in galacto-aminocyclohexanes that are linked through a secondary amine to a phytoceramide lipid having a cerotyl N-acyl group. Natural Killer T (NKT) cellular assays have resulted in the identification of an active compound, HS161, which has been found to promote NKT cell expansion in vitro in a similar fashion but more weakly than alphaGC. This compound stimulates the release of Interferon-gamma (IFNgamma) and Interleukin-4 (IL-4) in iNKT cell culture but with lower potency than alphaGC. The activation of Invariant Natural Killer T (iNKT) cells by this compound has been confirmed in flow cytometry experiments. Remarkably, when tested in mice, HS161 selectively induces a very strong production of IFN-gamma indicative of a potent Th1 cytokine profile. Overall, these data confirm the agonist activity of alphaGC lipid analogues having charged amino-substituted polar heads and their capacity to modulate the response arising from iNKT cell activation in vivo.

A medium fluorous Grubbs-Hoveyda 2nd generation catalyst for phase transfer catalysis of ring closing metathesis reactions

A fluorous Grubbs-Hoveyda metathesis catalyst supported on Teflon powder, that readily moves between the solid phase (Teflon) and the liquid phase (DMF) was prepared. By modulating the hydrophobicity of the reaction medium at the end of the reaction, the supported catalyst could be recovered by simple filtration even though the catalyst existed in a homogeneous state during the reaction. In RCM reactions, the catalyst could be reused up to three times with only a slight loss in reactivity with each subsequent cycle.

Synthesis of the C1-C17 fragment of the archazolids by complex cis-homodimer cross metathesis

Abstract Synthesis of the C1-C17 fragment of the archazolids is described featuring a complex cross-metathesis coupling reaction between a cis-homodimer (prepared by silyl-tethered ring-closing metathesis) and the Z,Z-terminal triene containing ‘eastern domain’ of the archazolid natural products. This cross-metathesis was only successful when using the cis- as opposed to the monomer or trans-homodimer, with the cis-dimer added batchwise to minimize cis/trans-isomerization. The product was obtained in an optimized 78% yield using the Hoveyda-Grubbs catalyst at 50 C in toluene.

A six-coordinated cationic ruthenium carbyne complex with liable pyridine ligands: Synthesis, structure, catalytic investigation, and DFT study on initiation mechanism

A novel six-coordinated high-valence cationic ruthenium carbyne complex bearing two liable pyridine ligands was prepared in high yield by the reaction of the ruthenium-based complex (IMesH2)(Cl)2(C 5H5N)2RuCHPh [IMesH2=1,3-dimesityl- 4,5-dihydroimida-zol-2-ylidene] with excess iodine as an oxidant in CH 2Cl2 at 25 C under N2. The new ruthenium carbyne-based complex shows moderate to good catalytic activity for ring-closing metathesis reactions. Importantly, no double bond isomerization by-product was produced at elevated reaction temperatures (100 C-137 C) in the reaction catalyzed by the synthesized ruthenium carbyne complex. A mechanism involving the in situ conversion of the ruthenium carbyne through the addition of an iodide to the carbyne carbon was also proposed, and DFT calculations were performed to explain the initiating mechanism.

Homogeneous vs heterogeneous polymerization catalysis revealed by single-particle fluorescence microscopy

A high-sensitivity and high-resolution single-particle fluorescence microscopy technique differentiated between homogeneous and heterogeneous metathesis polymerization catalysis by imaging the location of the early stages of polymerization. By imaging single polymers and single crystals of Grubbs II, polymerization catalysis was revealed to be solely homogeneous rather than heterogeneous or both.
