Henri Kagan and Kenso Soai Win 2026 Nobel Prize in Chemistry for Molecular Mirror Image Breakthrough
- •Henri B. Kagan and Kenso Soai received the 2026 Nobel Prize in Chemistry for solving a long-standing chemical puzzle regarding mirror-image molecules.
- •Kagan discovered that chemical reactions could produce a dominant amount of one mirror-image form, transforming reaction control.
- •Soai advanced the field with autocatalysis, creating reactions where products trigger the production of more of the same form, known as the Soai reaction.
- •Their breakthroughs significantly impact the development of medicines, flavors, fragrances, and materials, while explaining biological chemical imbalances.
Key Questions Answered
The 2026 Nobel Prize in Chemistry was awarded to Henri B. Kagan and Kenso Soai for their discovery of non-linear effects and autocatalysis in asymmetric organic synthesis. Their work explains why certain chemical reactions favor one molecular mirror-image form over another.
Developed by Kenso Soai, the Soai reaction involves a chemical process where the product helps the reaction generate more of the same mirror-image form. This process, known as autocatalysis, allows one specific mirror-image form to become strongly dominant.
The 2025 Nobel Prize in Chemistry was awarded to Susumu Kitagawa, Richard Robson, and Omar Yaghi for their pioneering work on metal-organic frameworks, or MOFs. Their research created a new class of porous crystalline materials capable of capturing, storing, and separating gases and chemicals.
