A propargylic amination approach toward chiral acyclic α-quaternary α-amino ketones is described. This Cu-catalyzed procedure could be performed open to air using commercially available amines as nucleophiles. The key success the use of rationally designed cyclic carbonates substrates, which can generate a Cu-bonded enolate zwitterionic intermediate upon decarboxylation. protocol features wide functional group tolerance and high asymmetric induction, with typical ee value higher than 93%, thus advances great step forward in challenging synthesis ketones.

A series of deep eutectic solvents (DESs), consisting protic ionic liquids (PILs) and amines, feature effective catalytic activity for the fixation CO2 to cyclic carbonates at ambient temperature pressure without any additives. Good yields are achieved (up 99%), no obvious deactivation in is found after five cycles. Mechanistic research reveals that epoxides activated simultaneously through synergistic catalysis PILs amines.
