Alkynylation of Csp2 (O)?H Bonds Enabled by Photoredox-Mediated Hydrogen-Atom Transfer

The development of new hydrogen-atom transfer (HAT) strategies within the framework of photoredox catalysis is highly appealing for its power to activate a desired C?H bond in the substrate leading to its selective functionalization. Reported here is the first photoredox-mediated hydrogen-atom transfer method for the efficient synthesis of ynones, ynamides, and ynoates with high regio- and chemoselectivity by direct functionalization of Csp2 (O)?H bonds. The broad synthetic application of this method has been demonstrated by the selective functionalization of C(O)?H bonds within complex molecular scaffolds.

Molecular modelling studies on ?7 nicotinic receptor allosteric modulators yields novel filter-based virtual screening protocol

The ?7 receptor is a member in the nicotinic acetylcholine receptor (nAChR) which has been implicated in several neurological disorders. Beside normal agonists and antagonists of alpha7 nAChRs, several studies revealed other types of molecules that are able to activate or deactivate ?7 receptors via allosteric binding; those are called positive allosteric modulators (PAMs) or negative allosteric modulators (NAMs), with the former having more pharmacological importance than the latter. Since both types of modulators are believed to bind to the same place in the intracavity of the transmembrane domain, it was important to differentiate between them in terms of structural features and their binding with the target receptor, and then use these specific characteristics as filters to discriminate PAMs from NAMS. To do that, modulators? physicochemical properties were investigated using two databases of known PAMs or NAMs which were then used to elucidate a specific pharmacophore for each class. Interestingly, PAMs were found to be relatively larger and more polar compared to NAMs, which was observed to carry a positive charge with double the number of cases than PAMs. Furthermore. a pharmacophore for each class was developed and the best PAMs pharmacophore was successfully able to pass 94% of tested PAMs and to eliminate 71% of NAMs, while the best NAM pharmacophore was able to pass 82% of NAMs and to filter out 85% of PAMs. Docking these known modulators into the alpha7 nAChRs allosteric site identified several amino acids that are key for specifically binding PAMs compared to NAMs. Next, these findings were employed in virtual screening and then seeding experiments were conducted to validate the developed pharmacophores usage as filters prior to the final docking. Interestingly, the number of retrieved PAMs in the final docking list was improved by up to five-fold compared to the non-filtered protocol, which clearly indicates for the efficiency of our protocol to pick true PAMs over decoys. Hence, the pharmacophore-based filtering technique developed in this work can act as a valuable tool in the pursuit of new, potent PAM molecules as therapeutically useful modulators of the alpha7 nicotinic receptors.

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.

Atroposelective Construction of Arylindoles by Chiral Phosphoric Acid-Catalyzed Cross-Coupling of Indoles and Quinones

Structurally novel atropisomeric arylindole frameworks have been successfully constructed through chiral phosphoric acid-catalyzed asymmetric cross-coupling of indoles and quinone derivatives in a precise regioselective manner. This approach features high convergence and functional group tolerance to efficiently deliver diverse heteroaryl atropisomers with excellent enantiocontrol. The dominant formation of axial chirality but not central chirality, as the major unmet challenge for this type of reactions, was conquered by the rational and accurate modulation of the electronic and steric effects on both coupling partners. Preliminary investigation demonstrated the practicality of such axially chiral arylindoles as chiral ligands in asymmetric catalysis.
