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.

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.

A concise synthetic route to the conduritols from pentoses

A short synthetic strategy for preparation of the conduritols is described. The key step employs a zinc-mediated fragmentation of protected methyl 5-deoxy-5-iodo-D-pentofuranosides followed by an allylation of the intermediate aldehyde in the same pot. The allylation is performed with 3-bromopropenyl benzoate and occurs with good diastereoselectivity. An amino group can be introduced in the product by trapping the intermediate aldehyde as the imine prior to the allylation. The functionalised 1,7-octadienes, thus obtained, are converted into protected conduritols by ring-closing olefin metathesis. The Royal Society of Chemistry 2005.

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.

Ruthenium-arene-beta-carboline complexes as potent inhibitors of cyclin-dependent kinase 1: Synthesis, characterization and anticancer mechanism studies

A series of RuII-arene complexes (1-6) of the general formula [(eta6-arene)Ru(L)Cl]PF6 (arene=benzene or p-cymene; L=bidentate beta-carboline derivative, an indole alkaloid with potential cyclin-dependent kinases (CDKs) inhibitory activities) is reported. All the complexes were fully characterized by classical analytical methods, and three were characterized by X-ray crystallography. Hydrolytic studies show that beta-carboline ligands play a vital role in their aqueous behaviour. These complexes are highly active in vitro, with the most active complex 6 displaying a 3- to 12-fold higher anticancer activity than cisplatin against several cancer cell lines. Interestingly, the complexes are able to overcome cross-resistance to cisplatin, and show much lower cytotoxicity against normal cells. Complexes 1-6 may directly target CDK1, because they can block cells in the G2M phase, down-regulate the expression of CDK1 and cyclin B1, and inhibit CDK1/cyclin B in vitro. Further mechanism studies show that the complexes can effectively induce apoptosis through mitochondrial-related pathways and intracellular reactive oxygen species (ROS) elevation. Copyright

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 37366-09-9 is helpful to your research., Synthetic Route of 37366-09-9

Synthesis of NHC complexes by template controlled cyclization of beta-functionalized isocyanides

Reduction of the azido functions of the coordinated isocyanide ligands with Zn/NH4Cl/H2O in methanol leads to coordinated 2-amino functionalized isocyanides which cyclize to yield the complexes with a saturated NH,NH-stabilized NHC ligand 5a-5d or a benzannulated NH,NH-stabilized NHC ligand 8a-8d. The Zn/NH4Cl/H2O reduction method is of general applicability and allowed the generation of complex 11 bearing three saturated NH,NH-stabilized NHC ligands.
