Ephedrine‐Based Diselenide: A Promiscuous Catalyst Suitable to Mimic the Enzyme Glutathione Peroxidase (GPx) and to Promote Enantioselective C—C Coupling Reactions.

The ephedrine-based diselenide appears as a new promiscuous catalyst, able to generate optically active alcohols by addition of organozinc to aldehydes (up to 97% ee), and shows powerful GPx like activity, reducing H2O2 to water in only 16.33 min (eleven times faster than PhSeSePh).
