Summary: Enantiopure 1,2-amino alcohols derived from abundant amino acids were used in C-C bond-forming hydrogen-borrowing alkylation reactions for the first time. The use of Ph*COMe aryl ketone facilitated the reactions, preventing racemisation of the amine stereocentre. The Ph* and trityl groups could be easily cleaved in one pot to give GABA products without further purification, allowing the two steps to be performed in sequence without isolation of the hydrogen-borrowing intermediate, eliminating the need for column chromatography.

Summary: The cobalt-catalyzed asymmetric hydrogenation of indazole-containing enamides relevant to the synthesis of Zavegepant, a CGRP receptor antagonist, which is approved for the treatment of migraines, is described. Both neutral and cationic bis(phosphine)cobalt complexes were efficient precatalysts, providing excellent yield and enantioselectivities for related substrates, with key reactivity differences observed. The hydrogenation of the indazole-containing enamide was successfully scaled up to 20 g.

Summary: Visible-light-mediated heterogeneous photocatalysis is a promising method for organic transformations. However, accurately detecting and identifying photogenerated species, especially short-lived radical intermediates, remains challenging. In this work, a hybrid ion emitter integrated with a pico-liter heterogeneous photocatalytic reactor was developed for the rapid identification of transient radical intermediates produced under visible-light irradiation. This novel coupling device provides a powerful tool for exploring complex heterogeneous photochemical processes and their ultrafast initial transformations.

Summary: Transition metal nitrides have attracted much attention due to their unique structure and electrical properties, and they have great potential for electrocatalytic applications. This study successfully synthesized highly crystalline and mesoporous titanium carbonitride (MTiCN) materials using a combination of reactive templating approach and doping. The optimized MTiCN material exhibited considerable electrocatalytic hydrogen evolution reaction (HER) activity, which is close to the performance of commercial platinum/carbon catalysts. This work provides a simple solution for the rational design of porous transition metal carbon nitrides with excellent electrocatalytic properties.

Summary: An iron catalyzed reaction has been developed for the selective transformation of thiols to sulfinamides by a direct transfer of -O and free -NH2 groups. It operates under mild conditions, exhibits broad functional group tolerance, and does not require precious metal catalysts or additional oxidants. Preliminary mechanistic studies suggest the role of the alcoholic solvent as an oxygen atom donor.
