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.

Synthesis of thioglycoside analogues of maradolipid

We describe here the first synthesis of thioglycoside analogues of maradolipid, based on a new procedure for the synthesis of 1-thiotrehalose developed recently in our laboratories. The challenging alpha,alpha- (1?1?) thioglycosidic linkage was constructed by Schmidt’s inverse procedure in very high yield and excellent stereoselectivity. Subsequent protecting group manipulation and coupling with different fatty acids led smoothly to a group of symmetrical and unsymmetrical thiomaradolipids which would be of high value for biological studies.

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

The first chemical synthesis of novel MeO-3-GlcUA derivative of hyaluronan-based disaccharide to elucidate the catalytic mechanism of hyaluronic acid synthases (HASs)

The first chemical synthesis of MeO-3-GlcUAp(1 ?3)GlcNAc-UDP to elucidate the catalytic mechanism of hyaluronic acid synthases (HASs) is described. Construction of the desired beta(1 ?3)-linked disaccharide 10 was achieved very efficiently by coupling MeO-3-GlcUA donor 3 with the suitable protected GlcNTroc acceptor 4 using BF3Et2O as Lewis acid. Chemoselective removal of anomeric NAP, phosphorylation, hydrogenation, coupling with UMP-morpholidate, and finally complete deprotection gave the target compound 1 in good yield.

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.

Mitigating hERG inhibition: Design of orally bioavailable CCR5 antagonists as potent inhibitors of R5 HIV-1 replication

A series of CCR5 antagonists representing the thiophene-3-yl-methyl ureas were designed that met the pharmacological criteria for HIV-1 inhibition and mitigated a human ether-a-go-go related gene (hERG) inhibition liability. Reducing lipophilicity was the main design criteria used to identify compounds that did not inhibit the hERG channel, but subtle structural modifications were also important. Interestingly, within this series, compounds with low hERG inhibition prolonged the action potential duration (APD) in dog Purkinje fibers, suggesting a mixed effect on cardiac ion channels.
