Asymmetric cyanoesterification of vinylarenes by electrochemical copper catalysis. [PDF]
The heterodifunctionalization of alkenes is an efficient and straightforward method for the preparation of highly functionalized molecules. However, enantioselective introduction of two different carbon-based functional groups in a single step using readily accessible and inexpensive starting materials presents a significant challenge.

Copper(I)-catalyzed asymmetric alkylation of α-imino-esters
Asymmetric alkylation of enolates is one of the most direct and important reactions to prepare α-chiral carbonyl compounds. Except for the classical methods that rely on the use of chiral auxiliaries, asymmetric catalysis emerged as a powerful tool ...

Identification of a tyrosine switch in copper-haem nitrite reductases
There are few cases where tyrosine has been shown to be involved in catalysis or the control of catalysis despite its ability to carry out chemistry at much higher potentials (1 V versus NHE). Here, it is shown that a tyrosine that blocks the hydrophobic
