5394-13-8, Name is 2-Bromobenzo[b]thiophene, belongs to benzothiophene compound, is a common compound. 5394-13-8In an article, authors is Atwater, Bruce, once mentioned the new application about 5394-13-8.

The ability to cross-couple secondary alkyl centers is fraught with a number of problems, including difficult reductive elimination, which often leads to beta-hydride elimination. Whereas catalysts have been reported that provide decent selectivity for the expected (non-rearranged) cross-coupled product with aryl or heteroaryl oxidative-addition partners, none have shown reliable selectivity with five-membered-ring heterocycles. In this report, a new, rationally designed catalyst, Pd-PEPPSI-IHeptCl, is demonstrated to be effective in selective cross-coupling reactions with secondary alkyl reagents across an impressive variety of furans, thiophenes, and benzo-fused derivatives (e.g., indoles, benzofurans), in most instances producing clean products with minimal, if any, migratory insertion for the first time. A wide variety of five-membered-ring heterocycles were successfully cross-coupled to secondary alkyl zinc reagents with the new precatalyst Pd-PEPPSI-IHeptCl, which features a bulky N-heterocyclic carbene ligand. This catalyst suppresses migratory-insertion (rearrangement) pathways, and the desired products are thus formed with high selectivity.

Haloaroylmethylidenephosphoranes 3 can be subjected to Pd(o) mediated C-C coupling reactions to yield diaryl-, arylhetaryl-, dihetaryl, arylethenylaryl/hetaryl- and arylethynylaryl/hetaryl-carbonylmethylidenephosphoranes 4-9. Suzuki-Kumada reactions can also be run in a one-step procedure from (haloaroylmethyl)triphenylphosphonium bromides 2. Compounds 4-9 are air-stable phosphoranes which undergo formal Wittig-olefination reactions with aldehydes 10 under benzoic acid catalysis. C-C coupling reaction and Wittig olefination can also be performed in a one-step procedure. Preliminary experiments have been performed to carry out the synthesis on a solid support. Applications to the chain elongation and functionalisation of the chain terminus in a C-7 substituted estra-1,3,5(10)-triene 14 and a C-16 substituted estra-1,3,5(10),6-tetraene 12 are shown.

In an effort to identify selective for the estrogen receptor subtype ERbeta, a series of aryl benzthiophenes was synthesized. In a radioligand binding assay and reporter gene assat in HeLa and SH-SY5Y cells, compound were characterized as ERbeta-selective agonists. By targeting ERbeta in the brain, these compounds could lead to drugs able to separate the beneficial effects of estrogens on mood, learning, and memory from side effects such as the stimulation of edometrial and breast cancer.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 6287-82-7, 2,3-Dibromobenzo[b]thiophene, introducing its new discovery.

A convenient procedure for the carbonylative synthesis of isoindoloquinazolinones has been developed. Using 1,2-dibromobenzenes and 2-aminobenzyl amine as substrates and palladium as the catalyst, the desired products were isolated in moderate to good yields with the installation of two molecules of carbon monoxide. Notably, this is the first example of carbonylative synthesis of batracylin analogues. This journal is the Partner Organisations 2014.

An important 13C NMR shielding effect on carbons bearing a heavy chalcogen is demonstrated.This effect is parallel to that induced by iodine, but to a lesser extent.For acyclic compounds and for partially saturated heterocycles, there is an excellent linear correlation between the 13C chemical shifts of carbons bearing a chalcogen and carbons bearing a halogen atom in the corresponding compound.The linearity of the relationship is less satisfactory with heteroaromatic compounds.
