Reactivity of several deactivated 3-aminobenzo[b]thiophenes in the Buchwald-Hartwig C-N coupling. Scope and limitations

Di(hetero)arylamines were prepared in moderate to high yields by Buchwald-Hartwig C-N coupling of bromobenzenes bearing electron-withdrawing groups and of a bromobiphenyl with several methyl 3-aminobenzo[b]thiophene-2-carboxylates, using the coupling conditions for heteroaromatic amines [Pd(OAc)2, Xantphos, Cs2CO3 in dioxane, 120 C]. The use of these aminobenzo[b]thiophenes as coupling components avoids the step of changing the amino group into a bromine atom, like we have done before to perform C-N couplings using the corresponding 3-bromobenzo[b]thiophenes. Nevertheless, the couplings using the methyl 3-aminobenzo[b]thiophene-2-carboxylates were only successful with bromobenzenes bearing electron-withdrawing groups and a bromobiphenyl or with electron deficient rings such us as bromopyridines. Using the latter compounds, different substituted 6H-benzothieno[3,2-d]pyrido[1,2-a]pyrimid-6-ones were obtained by C-N coupling followed by an intramolecular cyclization. These tetracyclic compounds may have interesting biological activity like it was already demonstrated by us for the non substituted derivative.

Design of reversible multi-electron redox systems using benzochalcogenophenes containing aryl and/or ferrocenyl fragments

2,3-Disubstituted benzo[b]thiophenes, 1,3-disubstituted benzo[c]thiophenes, and 1,3-disubstituted benzo[c]selenophene have been systematically and selectively synthesized from benzo[b]thiophene or phthaloyl dichloride as a starting material, respectively. Characterization of the molecules was performed by physical and spectroscopic means and X-ray crystallographic analyses. The cyclic voltammograms of the chalcogenophene derivatives containing aryl fragments showed well-defined reversible both anodic and cathodic steps derived from the unusually stable 5pi chalcogenophene radical cations and 7pi chalcogenophene radical anions. The cyclic voltammograms of the novel chalcogenophene derivatives containing ferrocenyl fragments showed a well-defined reversible cathodic step derived from the unusually stable 7pi chalcogenophene radical anions and two distinct reversible anodic steps derived from ferrocenium cations separated from each other by a thiophene-heterocycle. The radical character of several novel 7pi chalcogenophene radical anions was measured by ESR spectroscopy.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 6287-82-7, you can also check out more blogs about6287-82-7

Nickel-catalyzed difunctionalization of unactivated alkenes initiated by unstabilized enolates

This report demonstrates the possibility of a nickel-catalyzed difunctionalization of unactivated alkenes initiated by an unstabilized enolate nucleophile. The process tolerates a diverse range of electrophiles, including aryl, heteroaryl, alkenyl, and amino electrophiles. An electron-deficient phosphine ligand and a tetrabutylammonium salt additive were crucial for promoting efficient vicinal difunctionalization.

Identification of fused-ring alkanoic acids with improved pharmacokinetic profiles that Act as G protein-coupled receptor 40/free fatty acid receptor 1 agonists

The G protein-coupled receptor 40 (GPR40)/free fatty acid receptor 1 (FFA1) has emerged as an attractive target for a novel insulin secretagogue with glucose dependency. We previously identified phenylpropanoic acid derivative 1 (3-{4-[(2?,6?-dimethylbiphenyl-3-yl)methoxy]-2-fluorophenyl} propanoic acid) as a potent and orally available GPR40/FFA1 agonist; however, 1 exhibited high clearance and low oral bioavailability, which was likely due to its susceptibility to beta-oxidation at the phenylpropanoic acid moiety. To identify long-acting compounds, we attempted to block the metabolically labile sites at the phenylpropanoic acid moiety by introducing a fused-ring structure. Various fused-ring alkanoic acids with potent GPR40/FFA1 activities and good PK profiles were produced. Further optimizations of the lipophilic portion and the acidic moiety led to the discovery of dihydrobenzofuran derivative 53 ((6-{[4?-(2-ethoxyethoxy)-2?,6?-dimethylbiphenyl-3-yl]methoxy} -2,3-dihydro-1-benzofuran-3-yl)acetic acid), which acted as a GPR40/FFA1 agonist with in vivo efficacy during an oral glucose tolerance test (OGTT) in rats with impaired glucose tolerance.

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 4923-87-9 is helpful to your research. Reference of 4923-87-9

A new synthetic approach to 6-unsubstituted phenanthridine and phenanthridine-like compounds under mild and metal-free conditions

A new and mild synthetic approach for the synthesis of 6-unsubstituted phenanthridine and phenanthridine-like compounds under metal-free conditions at room temperature has been developed. The strategy involved a tandem azide rearrangement/intramolecular annulation and oxidation reactions of biarylmethyl azide precursors to obtain the desired products in up to 99% yields with high regioselectivity.

Addition Reactions of Benzothiophen. Part 3. Addition and Ring-opening Reactions with Phenolic Ethers

In the presence of aluminium chloride, anisole, phenetole, diphenyl ether, and (methylthio)benzene are added rapidly across the 2,3-bond in benzothiophen to give, inter alia, a mixture of 2- and 3-(p-substituted aryl)-2,3-dihydrobenzothiophens (3) and (4).Contrary to expectation, the 2-isomer predominates in all cases, and the addition is irreversible.Reaction with anisole also leads to a novel ring-opened product, viz. (E)-4-methoxy-2′-methylthiostilbene (9a), which was synthesised unambigiuously.It is believed that benzothiophen is S-methylated by PhOMe-AlCl3 in a ‘push-pull’ reaction, and that the resulting positive charge is delocalised into the ring, thus allowing the 2-position to participate in electrophilic attack on a second molecule of anisole.The resulting quadrivalent sulphur intermediate achieves stabilisation by means of a rapid ring-opening reaction.Other aromatic methyl ethers give analogous products, but phenetole diphenyl ether, and (methylthio)benzene do not promote ring-opening.The ring-opening reaction is aided by the addition of MeBr- or EtBr-AlCl3; even phenetole will then undergo ring-opening.Under these conditions the S-alkyl group in the ring-opened product comes from the starting ether, and not from the added MeBr or EtBr.
