The Role of Organocatalysts in Asymmetric Aldol Reactions
Quick fact
A simple amino acid, proline, can catalyze asymmetric aldol reactions with impressive enantioselectivity, achieving up to 97% enantiomeric excess (ee) in certain cases—demonstrating that complex stereocontrol doesn't require metals or enzymes.
Why this is interesting
Have you ever wondered how chemists create molecules that are mirror-image twins, yet one is a life-saving drug and the other is ineffective or harmful? The secret often lies in tiny organic catalysts that control the shape of molecular hands.
