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
