Mannich-type reactions of aryl, heteroaryl, and isomerizable alkyl N-Eoc imines and ot-substituted nitroacetates gave products in 91% to >99% ee and high anti-selectivity (Scheme 4) [22], which were successfully converted into ot,p-diamino acids with a-tetrasubstituted stereocenter. Catalyst loading was successfully... [Pg.8]
