The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Atropisomerism is a type of stereoisomerism that results from severely hindered rotation around a single bond. If the barrier to rotation is sufficiently high then the two atropisomers will be stable ...

Pharmaceutical process chemists use resolutions, or the separation of enantiomers from racemic mixtures, more than 60% of the time to generate chiral compounds. Among resolution methods, ...

This study achieved efficient and highly enantioselective synthesis of chiral α-aryl cyclic ketones through visible light photocatalysis-driven racemization, with the main advantages being: 1. Under ...
