4.2.3 Direct catalytic enantioselective Mannich reactions
- Direct Mannich reactions have been explored with both metal catalysts and organocatalysts more
intensively than aldol variants possibly due to the lack of retro reactions, which are normally problematic in
aldol reaction.
- List succeeded in using acetaldehyde as nucleophiles in direct Mannich reactions.

Enantioselective Strecker reactions
- Jacobsen reported one of the first catalytic, asymmetric variants of Strecker reaction, using chiral urea as a
catalyst. The hydrogen bonding between imine and catalyst is responsible for the induction of chirality.
