Formation of α-methylene-β-hydroxy carboxylic acidderivatives by nucleophile catalyzed condensation between an aldehyde and an acrylate derivative. Deracemization A process that allows the formation of an enantiomerically enriched compound from the racemic without apparent structural changes. These reactions ...
It combines carboxylic acid-derived redox-active esters with aldehyde sulfonyl hydrazones, utilizing Eosin Y as an efficient organophotocatalyst under visible light, leading to the desired cross-coupled products through subsequent fragmentation. Our approach provides a safer alternative to the traditional ...
The carboxylic acid modifiers control the alcohol adsorption affinity of the catalyst, resulting in tunable alcohol oxidation reactivity.
