Optically active a-amino acids are vital to life as building blocks of peptides, proteins, and many other natural products. Amino acids are also applied extensively as food additives, pharmaceuticals, and agrochemicals. Furthermore, amino acids are widely used in organic synthesis as targets, and as

The catalytic and asymmetric nitro-Mannich reaction of nitro compounds to α-imino esters catalyzed by chiral bisoxazoline-copper complexes [Eq. (1); Pg = protecting group] gave β-nitro-α-amino esters with excellent diastereo- and enantioselectivities. The reactions can be performed under ambient con
The development of CÀC bond-forming reactions that create two new stereogenic centers with high diastereo-and enantioselectivity in a single step can open new routes to highly valuable optically active compounds. The catalytic enantioselective addition to imines [1] belongs to this class of importan
