2026 Nobel Prize in Chemistry Recognizes Discoveries in Asymmetric Organic Synthesis
The 2026 Nobel Prize in Chemistry has been awarded to Henri B. Kagan of Université Paris-Sud, France, and Kenso Soai of Tokyo University of Science, Japan, for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis.

Their pioneering research has advanced our understanding of molecular chirality by showing how small initial imbalances between enantiomers can be amplified through chemical reactions.

Henri B. Kagan made fundamental contributions to asymmetric catalysis by identifying nonlinear effects, in which the enantiomeric composition of a catalyst does not necessarily correspond linearly to that of the product. Under certain conditions, such effects can enhance the enantiomeric excess of the product, offering new insights into stereoselective catalysis.

Kenso Soai developed the landmark Soai reaction, demonstrating asymmetric autocatalysis in which a chiral product catalyzes its own formation. This reaction showed how a small initial chiral imbalance can be amplified under suitable conditions, providing an important experimental model for studying chirality amplification.
These discoveries have deepened our understanding of asymmetric synthesis and provided valuable insights into possible origins of molecular homochirality. They also demonstrate the value of fundamental mechanistic research in advancing selective chemical transformations.
