Davis, Holly J. published the artcileIon Pair-Directed Regiocontrol in Transition-Metal Catalysis: A Meta-Selective C-H Borylation of Aromatic Quaternary Ammonium Salts, Related Products of chlorides-buliding-blocks, the publication is Journal of the American Chemical Society (2016), 138(39), 12759-12762, database is CAplus and MEDLINE.

The use of noncovalent interactions to direct transition-metal catalysis is a potentially powerful yet relatively underexplored strategy, with most investigations thus far focusing on using hydrogen bonds as the controlling element. We have developed an ion pair-directed approach to controlling regioselectivity in the iridium-catalyzed borylation of two classes of aromatic quaternary ammonium salts, leading to versatile meta-borylated products. By examining a range of substituted substrates, this provides complex, functionalized aromatic scaffolds amenable to rapid diversification and more broadly demonstrates the viability of ion-pairing for control of regiochem. in transition-metal catalysis.

Ostacolo, Carmine published the artcileSynthesis and Pharmacological Characterization of Conformationally Restricted Retigabine Analogues as Novel Neuronal Kv7 Channel Activators, Application of ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Journal of Medicinal Chemistry (2020), 63(1), 163-185, database is CAplus and MEDLINE.

Kv7 K⁺ channels represent attractive pharmacol. targets for the treatment of different neurol. disorders, including epilepsy. In this paper, 42 conformationally restricted analogs of the prototypical Kv7 activator retigabine have been synthesized and tested by electrophysiol. patch-clamp experiments as Kv7 agonists. When compared to retigabine (0.93 ± 0.43 μM), the EC₅₀s for Kv7.2 current enhancements by compound I (0.08 ± 0.04 μM) were lower, whereas no change in potency was observed for II (0.63 ± 0.07 μM). In addition, compared to retigabine, I and II showed also higher potency in activating heteromeric Kv7.2/Kv7.3 and homomeric Kv7.4 channels. Mol. modeling studies provided new insights into the chem. features required for optimal interaction at the binding site. Stability studies evidenced improved chem. stability of I and II in comparison with retigabine. Overall, the present results highlight that the N5-alkylamidoindole moiety provides a suitable pharmacophoric scaffold for the design of chem. stable, highly potent and selective Kv7 agonists.

Hell, Sandrine M. published the artcileHydrosulfonylation of Alkenes with Sulfonyl Chlorides under Visible Light Activation, Related Products of chlorides-buliding-blocks, the publication is Angewandte Chemie, International Edition (2020), 59(28), 11620-11626, database is CAplus and MEDLINE.

Sulfonyl chlorides are inexpensive reactants extensively explored for functionalization, but never considered for radical hydrosulfonylation of alkenes. Herein, the authors report that tris(trimethylsilyl)silane is an ideal hydrogen atom donor enabling highly effective photoredox-catalyzed hydrosulfonylation of electron-deficient alkenes with sulfonyl chlorides. To increase the generality of this transformation, polarity-reversal catalysis (PRC) was successfully implemented for alkenes bearing alkyl substituents. This late-stage functionalization method tolerates a remarkably wide range of functional groups, is operationally simple, scalable, and allows access to building blocks which are important for medicinal chem. and drug discovery.

Khorsandi, Zahra published the artcileVisible light-driven direct synthesis of ketones from aldehydes via C-H bond activation using NiCu nanoparticles adorned on carbon nano onions, Recommanded Product: (3-Chloro-5-cyanophenyl)boronic acid, the publication is Molecular Catalysis (2021), 111987, database is CAplus.

An efficient, straightforward and high yield synthetic approach is described for the direct synthesis of diaryl ketones via the C-H bond activation of aldehydes using Ni-Cu nanoparticles adorned on carbon nano onions as an efficient heterogeneous catalyst under the irradiation of a mercury-vapor lamp (400 w) via simple workup. This C-H bond activation reaction appears simple and convenient with a wide substrate scope in view of its excellent synthesis prowess as illustrated in the preparation of new-approved anti-Alzheimer and anti-HIV medicinal compounds under greener and mild reaction conditions; catalyst could be recycled and reused five times without any loss of catalytic activity.

Spare, Lawson K. published the artcileA continuous flow protocol to generate, regenerate, load, and recycle chlorotrityl functionalised resins, Product Details of C19H14Cl2, the publication is Reaction Chemistry & Engineering (2019), 4(7), 1309-1317, database is CAplus.

From a screen of chlorinating agent concentration, flow rates, and reagent addition methodologies, a continuous flow protocol to activate, reactivate, and recycle both 2-chlorotrityl chloride functionalised polystyrene and trityl-hydroxy ChemMatrix functionalised resins was established. This protocol significantly reduced resin loading periods. Under batch conditions, previously reported trityl resin chlorination protocols are effected over 1-24 h whereas the continuous flow chlorination procedure was completed within 10 min. Further amino acid residue tethering to the resin was effected within 5 min as opposed to the 2-h loading period typically applied under batch conditions. Moreover, an injection-based continuous-flow methodol. proved effective in maintaining the chiral integrity of Fmoc-His(Trt)-OH, Fmoc-Cys(Trt)-OH, and Fmoc-Ser(t-Bu)-OH, which are susceptible to direct base-induced epimerisation. Further, through incorporating the optimized AcCl resin chlorination protocol into a continuous flow solid-phase peptide construction procedure, a facile and resin recyclable approach to conduct SPPS was established.
