Catalytic asymmetric CO 2 utilization reaction for the enantioselective synthesis of chiral 2-oxazolidinones.

Catalytic asymmetric bromocyclizations of in situ generated carbamic acids from CO 2 and allylamines were achieved via the use of a BINOL-derived chiral bifunctional selenide catalyst bearing a hydroxy group. Chiral 2-oxazolidinone products as important pharmaceutical building blocks were obtained with good enantioselectivities by the present catalytic asymmetric CO 2 utilization reactions.
