https://www.selleckchem.com/products/aebsf-hcl.html Conglomerate crystallization is required for many deracemization or enantioenrichment protocols. Here, we report the metal-mediated mechanochemical transformation of racemic compounds of some proteinogenic amino acids - valine, leucine and isoleucine - into their corresponding conglomerates. Specifically, ZnO has the ability to promote and stabilize the conglomerate phase of these amino acids to an extent where the racemic compound is not observed.Cobalt decorated nitrogen-doped carbon bowls (Co@NCB) have been successfully constructed by impregnating bowl-like resin particles with cobalt salt followed by annealing. The cobalt exists in the following two forms in the obtained Co@NCB Co nanoparticles and CoN4. The Co@NCB outperforms the commercial Pt/C in the oxygen reduction reaction in terms of half-wave potential and stability. When Co@NCB is applied in zinc-air batteries, a high open-circuit voltage, excellent power density, and satisfactory stability are achieved.The asymmetric catalytic hydrogenation of olefins is one of the most widely studied and utilised transformations in asymmetric synthesis. This straightforward and atom-economical strategy can provide excellent enantioselectivity for a broad variety of substrates and is widely relevant for both industrial applications and academic research. In many instances the hydrogenation is stereospecific in the regard that the E-Z-geometry of the olefin governs the stereochemistry of the hydrogenation, producing an enantiodivergent outcome. Interestingly, the possibility to hydrogenate E- and Z-isomer mixtures to a single stereoisomer in an enantioconvergent manner has been reported. This avoids the need for synthesis of geometrically pure alkene starting materials and therefore constitutes a significant practical advantage. This review article aims to provide an overview of the different stereochemical outcomes in the hydrogenation of olefins. Although the field i
