2-Aminoimidazole-based antagonists of the 5-HT6 receptor ? A new concept in aminergic GPCR ligand design

A new strategy in the design of aminergic GPCR ligands is proposed ? the use of aromatic, heterocyclic basic moieties in place of the evergreen piperazine or alicyclic and aliphatic amines. This hypothesis has been tested using a benchmark series of 5-HT6R antagonists obtained by coupling variously substituted 2-aminoimidazole moieties to the well established 1-benzenesulfonyl-1H-indoles, which served as the ligands cores. The crystallographic studies revealed that upon protonation, the 2-aminoimidazole fragment triggers a resonance driven conformational change leading to a form of higher affinity. This molecular switch may be responsible for the observed differences in 5-HT6R activity of the studied chemotypes with different amine-like fragments. Considering the multiple functionalization sites of the embedded guanidine fragment, diverse libraries were constructed, and the relationships between the structure and activity, metabolic stability, and solubility were established. Compounds from the N-(1H-imidazol-2-yl)acylamide chemotype (10a?z) exhibited high affinity for 5-HT6R and very high selectivity over 5-HT1A, 5-HT2A, 5-HT7 and D2 receptors (negligible binding), which was attributed to their very weak basicity. The lead compound in the series 4-methyl-5-[1-(naphthalene-1-sulfonyl)-1H-indol-3-yl]-1H-imidazol-2-amine (9i) was shown to reverse the cognitive impairment caused by the administration of scopolamine in rats indicating procognitive potential.

Regioselective Functionalization of Enamides at the alpha-Carbon via Unsymmetrical 2-Amidoallyl Cations

A new method to functionalize enamides via an intermediacy of unsymmetrical 2-amidoallyl cations is reported. Generated under mild Br¡ãnsted acid catalysis, these reactive species were found to undergo addition with various nucleophiles at the less substituted alpha-carbon to produce highly substituted enamides in high yields with complete control of regioselectivity.

Atom-economical selenation of electron-rich arenes and phosphonates with molecular oxygen at room temperature

Organoselenium and selenophosphorus compounds are ubiquitously found in biologically active compounds, agrochemicals, functionalized materials etc. Although selenium is a micronutrient and an essential trace element, its contamination/consumption in higher concentrations is extremely dangerous. However, most of the previous selenation reactions generate toxic selenium waste as a by-product. Thus development of green synthetic protocols of these compounds is in high demand. We report herein a mild base-catalyzed cross-dehydrogenative coupling (CDC) between electron-rich arenes and phenylselenol to afford 3-selenylindole or selenylated phenols under air at room temperature. Interestingly, in the presence of a base and oxygen, the phenylselenol is converted into the diphenyldiselenide and provides almost quantitative yield. Similarly, a mild synthesis of selenophosphates was also achieved from the corresponding diorganyldiselenide or phenylselenols and nucleophilic phosphonates in a “dump and stir” manner under an oxygen balloon without a base or catalyst. From the preliminary mechanistic studies for selenation of indoles and phosphonates with TEMPO and EPR of the reaction mixture, it was evident that the reaction proceeds through the anionic pathway, which is in sharp contrast to the previous literature. The present reactions proceed smoothly under the mild conditions, furnishing high to almost quantitative yields in several cases. The reaction is easily scaled up to gram scale and has been demonstrated for the synthesis of an anti-HIV zidovudine (AZT) analogue.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Recommanded Product: 4-Cyanoindole, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 16136-52-0

Copper-Catalyzed Three-Component Reaction for Regioselective Aryl- and Heteroarylselenation of Indoles using Selenium Powder

A new and efficient copper-catalyzed C3 aryl- and heteroarylselenation of indoles employing selenium powder has been developed. The advantages of this chemistry involve the use of cheap selenating reagents, tolerance of a variety of functional groups, and practicality. In addition, this protocol has been further elaborated in an intramolecular phenylselenation of a (hetero) aryl C-H bond to construct an important motif of benzoselenopheno[3,2-b]indole. A preliminary mechanism study suggests that the reaction starts with a Ullman-type selenation between aryl iodides and selenium, followed by an oxidative cross-coupling with indole. The utility of this method has been demonstrated in an efficient gram-scale synthesis and an application to the synthesis of tubulin polymerization inhibitor.
