A unified strategy was conceived and implemented to deliver conformationally constrained anilides based on their preferred cis-amide conformers. The imidazole/triazole mimicing amide bonds were designed, building upon an earlier discovery of a novel series of tricyclic lactams MK2 kinase inhibitors. This approach enabled rapid, modular synthesis of structurally novel analogs. The efficient SAR development led to the discovery of low mol. weight and potent MK2 non-ATP competitive inhibitors with good ligand efficiency, which led to improved permeability and oral exposure in rats.

A photoredox/nickel dual catalyzed reductive hydrobenzylation of alkynes and benzyl chlorides by employing alkyl amines as a stoichiometric reductant is described. This synergistic protocol proceeds via Markovnikov-selective migratory insertion of an alkyne into nickel hydride, followed by cross-coupling with benzyl chloride, providing facile access to important 1,1-disubstituted olefins. This reaction enables the generation of nickel hydride by utilizing readily available alkyl amines as the hydrogen source. The mild conditions are compatible with a wide range of aryl and alkyl alkynes as well as chlorides.

Kwasny, Michael T. published the artcileThermodynamics of counterion release is critical for anion exchange membrane conductivity, HPLC of Formula: 23616-79-7, the publication is Journal of the American Chemical Society (2018), 140(25), 7961-7969, database is CAplus and MEDLINE.

As the field of anion exchange membranes (AEMs) employs an increasing variety of cations, a critical understanding of cation properties must be obtained, especially as they relate to membrane ion conductivity Here, to elucidate such properties, metal cation-based AEMs, featuring bis(norbornene) nickel, ruthenium, or cobalt complexes, were synthesized and characterized. In addition, isothermal titration calorimetry (ITC) was used to probe counterion exchange thermodn. in order to understand previously reported differences in conductivity The ion conductivity data reported here further demonstrated that nickel-complex cations had higher conductivity as compared to their ruthenium and cobalt counterparts. Surprisingly, bulk hydration number, ion concentration, ion exchange capacity, and activation energy were not sufficient to explain differences in conductivity, so the thermodn. of metal cation-counterion association were explored using ITC. Specifically, for the nickel cation as compared to the other two metal-based cations, a larger thermodn. driving force for chloride counterion release was observed, shown through a smaller ΔH_tot for counterion exchange, which indicated weaker cation-counterion association The use of ITC to study cation-counterion association was further exemplified by characterizing more traditional AEM cations, such as quaternary ammoniums and an imidazolium cation, which demonstrated small variances in their enthalpic response, but an overall ΔH_tot similar to that of the nickel-based cation. The cation hydration, rather than its hydration shell or the bulk hydration of the membrane, likely played the key role in determining the strength of the initial cation-counterion pair. This report identifies for the first time how ITC can be used to exptl. determine thermodn. quantities that are key parameters for understanding and predicting conductivity in AEMs.
