The current approach to improve and tune the enantioselective performances of transition-metal catalysts for asymmetric synthesis is mostly focused to modifications of the steric properties of the ancillary ligands of the active metal. Nevertheless, it is also known that electrostatic

The direct three-component aza-Diels-Alder reaction of aromatic aldehyde, aromatic amine, and 2-cyclohexen-1-one was catalyzed by hen egg white lysozyme for the first time. Under the optimized conditions investigated in this paper, the enzyme-catalyzed aza-Diels-Alder reaction gave yields up to 98%

Conjugate addition of Et(2)Zn to 2-cyclohexen-1-one catalyzed by Cu(OTf)(2) combined with an azolium salt derived from (S)-leucinol produced the corresponding (S)-adduct, while the use of Cu(acac)(2) in combination with the same ligand afforded the (R)-adduct as a major product.
