(3R,4R)-2,2,5,5-Tetraphenyltetrahydrofuran-3,4-diol Assisted, L-proline- Catalyzed Michael Addition of Acetone to Nitroalkenes

Addition of catalytic amounts of the chiral title furandiol (TPF) in the proline-catalyzed Michael addition of acetone to nitroalkenes results in a significant improvement of the enantioselectivity.
