Enantio- and diastereoselective mannich-type reactions of α-Cyano ketones with N-Boc aldimines catalyzed by chiral bifunctional urea
The catalytic enantioselective electrophilic Mannich-type reaction promoted by chiral bifunctional organocatalysts is described. The treatment of a-cyano ketones with N-Boc-aldimines under mild reaction conditions afforded the corresponding β-amino-α-cyan

Highly enantioselective conjugate addition of fluoromalonates to nitroalkenes using bifunctional organocatalysts
The enantioselective conjugate addition of fluoromalonates to aromatic nitroalkenes catalyzed by chiral amine-thiourea bifunctional organocatalysts generated a stereocenter at the carbon bearing the aromatic group and an adjacent prochiral center from the
