Ortho and remote metalation – cross coupling strategies. Total synthesis of the naturally occurring fluorenone dengibsinin and the azafluoranthene alkaloid imeluteine

The total synthesis of the naturally occurring fluorenone, dengibsinin (7a), and the azafluoranthene alkaloid, imeluteine (30e), is described. Using combined ortho metalation – cross coupling sequences that terminate in Friedel-Crafts (18b?6d) and remote metalation (21a,b?6c,d) reactions, the synthesis of fluorenone dimethyl ethers 6c and 6d is reported. 6c and 6d were shown not to be identical to dengibsinin dimethyl ether and dengibsin dimethyl ether, respectively, derived from the natural products. This work, together with synthetic and structural evidence from Sargent and Talapatra, led to the reassignment of structures for dengibsinin (7a) and dengibsin (7b). Using the metalation – cross coupling approach, the synthesis of the reassigned dengibsinin (7a) is presented. Two alternate unsuccessful approaches to imeluteine are briefly described (31+32 and 33+34). The successful approach incorporates the remote metalation – double cyclization, 43?44, as the key step.

A de Novo-Designed Monomeric, Compact Three-Helix-Bundle Protein on a Carbohydrate Template

De novo design and chemical synthesis of proteins and of other artificial structures that mimic them is a central strategy for understanding protein folding and for accessing proteins with new functions. We have previously described carbohydrates that act as templates for the assembly of artificial proteins, so-called carboproteins. The hypothesis is that the template preorganizes the secondary structure elements and directs the formation of a tertiary structure, thus achieving structural economy in the combination of peptide, linker, and template. We speculate that the structural information from the template could facilitate protein folding. Here we report the design and synthesis of three-helix-bundle carboproteins on deoxyhexopyranosides. The carboproteins were analyzed by CD, analytical ultracentrifugation (AUC), small-angle X-ray scattering (SAXS), and NMR spectroscopy, and this revealed the formation of the first compact and folded monomeric carboprotein, distinctly different from a molten globule. En route to this carboprotein we observed a clear effect originating from the template on protein folding.

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 14215-68-0 is helpful to your research., Synthetic Route of 14215-68-0

Sequential Directed Ortho Metalation-Boronic Acid Cross-Coupling Reactions. A General Regiospecific Route to Oxygenated Dibenzopyran-6-ones Related to Ellagic Acid

A general regiospecific synthesis of dibenzopyran-6-one derivatives 1a,c and 8a-i related to ellagic acid is described (Scheme I, Table I).The sequence involves directed ortho metalation-boronation of benzamides 4 to give the arylboronic acids 5, which, upon palladium-catalyzed cross-coupling with alkoxybromobenzenes 6 leads to the biphenylamides 7.BBr3 demethylation followed by acid-catalyzed cyclization affords pyranone 8.In this manner, the naturally occurring dibenzopyranones 1a, autumnariol (1c), and the heterocyclic analogue 13 (Scheme III) were efficiently prepared.

Mechanistic analysis of oxidative C-H cleavages using inter- and intramolecular kinetic isotope effects

A series of monodeuterated benzylic and allylic ethers were subjected to oxidative carbon-hydrogen bond cleavage to determine the impact of structural variation on intramolecular kinetic isotope effects in DDQ-mediated cyclization reactions. These values are compared to the corresponding intermolecular kinetic isotope effects that were accessed through subjecting mixtures of non-deuterated and dideuterated substrates to the reaction conditions. The results indicate that carbon-hydrogen bond cleavage is rate determining and that a radical cation is most likely a key intermediate in the reaction mechanism.

Synthesis of benzaldehyde-functionalized glycans: A novel approach towards glyco-SAMs as a tool for surface plasmon resonance studies

In recent years the interest in tools for investigating carbohydrateprotein (CPI) and carbohydrate-carbohydrate interactions (CCI) has increased significantly. For the investigation of CPI and CCI, several techniques employing different linking methods are available. Surface plasmon resonance (SPR) imaging is a most appropriate tool for analyzing the formation of self-assembled monolayers (SAM) of carbohydrate derivatives, which can mimic the glycocalyx. In contrast to the SPR imaging methods used previously to analyze CPI and CCI, the novel approach reported herein allows a facile and rapid synthesis of linker spacers and carbohydrate derivatives and enhances the binding event by controlling the amount and orientation of ligand. For immobilization on biorepulsive amino-functionalized SPR chips by reductive amination, diverse aldehyde-functionalized glycan structures (glucose, galactose, mannose, glucosamine, cellobiose, lactose, and lactosamine) have been synthesized in several facile steps that include olefin metathesis. Effective immobilization and the first binding studies are presented for the lectin concanavalin A.

Protecting group free synthesis of urea-linked glycoconjugates: Efficient synthesis of beta-urea glycosides in aqueous solution

A method for the protecting group free synthesis of beta-urea-linked glycoconjugates has been developed. The one step process, involving reactions between urea and d-glucose, N-acetyl-d-glucosamine or d-xylose in acidic aqueous solution, furnishes the corresponding beta-urea glycosides in modest yields. This simple and efficient procedure is applicable to the synthesis of beta-urea tethered amino acid-carbohydrate conjugates. This journal is the Partner Organisations 2014.

Reconstituting poly(glycerol phosphate) wall teichoic acid biosynthesis in vitro using authentic substrates

Wall teichoic acids (WTAs) are phosphate-rich anionic polymers that constitute a substantial portion of the Gram-positive cell wall. Recent work has demonstrated the importance of WTAs in cell shape, virulence and antibiotic resistance. These findings highlight WTA biosynthetic enzymes as attractive targets for novel antimicrobial agents. Due to challenges involved in the isolation of natural substrates, in vitro studies of the recombinant enzymes have largely employed soluble substrate analogues. Herein we present a semisynthetic approach to obtain the authentic precursor for WTA biosynthesis, Lipid alpha, complete with its polyisoprenoid lipid moiety. We show that this material can be used to reconstitute the activities of four enzymes involved in poly(glycerol phosphate) WTA biosynthesis in a detergent micelle. This work enables the creation of chemically defined and realistic systems for the study of interfacial catalysis by WTA biosynthetic machinery, which could aid efforts to discover and develop novel agents against WTA biosynthesis.

Synthesis and evaluation of various heteroaromatic benzamides as analogues of ?ylidene-benzamide cannabinoid type 2 receptor agonists

The CB2 receptor is an attractive target for the treatment of a wide range of diseases and pathological conditions. Compounds that selectively activate the CB2 receptor are desirable as this avoids CB1-mediated psychoactive effects. Heteroarylidene-benzamides have demonstrated efficacy as selective CB2 receptor agonists. We aimed to expand the structure-activity relationship studies of this series of compounds by investigating the heteroaromatic core via the synthesis and in vitro evaluation of a small library of various heteroaromatic benzamide analogues. As heteroaromatic amides are privileged scaffolds in drug design, methods to synthesise them are of interest. Concise and reliable synthetic strategies were developed to access these novel analogues. The ?ylidene-benzamide moiety is shown to be essential for CB activity as all amide derivatives exhibit no functional activity at either CB2 or CB1 receptors.
