title: Chiral primary-tertiary diamine catalysts derived from natural amino acids for syn-aldol reactions of hydroxy ketones.
abstract: A series of primary-tertiary diamine catalysts were designed and synthesized from primary natural amino acids. Application of these new chiral catalysts in direct aldol reactions of alpha-hydroxyketones showed very good catalytic activity (up to 97% yield) and high syn selectivity (up to syn/ anti = 30:1, 99% ee).
