A new primary-tertiary diamine catalyst is easily prepared in a few steps from inexpensive, commercially available, enantiopure materials. This organocatalyst can be effective catalyzed the direct asymmetric aldol and Mannich reactions. The anti-aldol products can be obtained with up to a 99:1 anti/syn ratio and >98 % ee, while the syn-Mannich products could be obtained with up to a 99:1 syn/anti ratio and >99 % ee. Catalyst 1c can be used efficiently on a large scale with the enantioselectivities of the anti-aldol and syn-Mannich reactions being maintained at the same level, which offers a great possibility for application in industry.
