(matrix presented) An air-stable storable, and highly selective chiral Lewis acid catalyst for asymmetric Mannich-type reactions has been developed. The catalyst can be stored for more than three months in air at room temperature without loss of activity.
Catalytic enantioselective addition of propionate units to imines: An efficient synthesis of anti-α-methyl-β-amino acid derivatives

, p. 4185 - 4190 (2007/10/03)
Optically active anti-α-methyl-β-amino acid derivatives have been prepared based on catalytic enantioselective addition of propionate units to simple and inert imines using a chiral zirconium complex. High reactivity and selectivity with wide substrate sc
