The first examples of highly enantioselective organocatalytic Mannich reactions of ferrocenecarbaldehyde are disclosed. The reaction is catalyzed by simple amino acids and gives access to β-arylamino-β-ferrocenylketones in high yields and with up to 99% ee.
The diastereo- and enantioselective syntheses of trans-cycloalkyl amines was accomplished through a three-step sequence consisting of: (1) asymmetric transfer hydrogenation through dynamic kinetic resolution of bicyclic and monocyclic α-substituted ketones using HCO 2 H/Et 3 N as the hydrogen source and TsDPEN-based Ru(II) catalysts, (2) nucleophilic hydroxyl to azide substitution...
