The Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Chemistry to Henri B. Kagan and Kenso Soai for discoveries involving non-linear effects and autocatalysis in asymmetric organic synthesis. The work helps explain how a chemical reaction can produce an excess of one molecular mirror image and has informed the design of reactions used to make pharmaceuticals.
The Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Chemistry to Henri B. Kagan and Kenso Soai for discoveries on non-linear effects and autocatalysis in asymmetric organic synthesis. Their work helps explain how chemical reactions can favor one of two mirror-image forms of a molecule, a problem relevant to both the chemistry of living organisms and the development of pharmaceuticals.
The Academy said Kagan made a decisive advance in 1986, discovering a way to manipulate reactions so they produced a greater excess of one molecular mirror image than chemists had previously thought possible. Soai’s work extended that line of research: a key publication in 1995 described a reaction designed to have the potential to become homochiral, and in 2003 he presented a reaction that formed only one of the two possible mirror-image products, according to the prize announcement.
The Nobel recognizes the pair’s contributions to understanding homochirality—the predominance of one molecular handedness. Many molecules occur in two forms that are mirror images of each other. The Academy says amino acids in the proteins of living cells are found in one of these forms, while the opposite form is rarely found in nature.
Kagan, born in 1930 in Boulogne-Billancourt, France, is a professor emeritus at the institution now known as Université Paris-Saclay, formerly Université Paris-Sud. Soai, born in 1950 in Hiroshima, Japan, is a professor emeritus at Tokyo University of Science. The 12 million Swedish kronor prize will be divided equally between them.
How Molecular Handedness Shapes Chemistry
The prize highlights a fundamental question in chemistry: how a reaction can favor one of two mirror-image structures rather than producing equal amounts of both. The Academy describes the laureates’ work as providing a way to understand how homochirality can emerge. This matters because molecular handedness is a defining feature of life’s chemistry, including the amino acids used to build proteins.
The research also has practical relevance. As the Academy notes, the two mirror forms of a molecule can interact differently with living systems, so drug developers often need to control which form a reaction produces. Kagan and Soai’s discoveries have been decisive for chemists designing reactions for pharmaceutical manufacture, although the prize announcement does not quantify their effect on particular medicines or industrial processes.

From Kagan’s 1986 Finding to Soai’s Reaction
In ordinary reactions that produce two mirror-image molecules, chemists may obtain equal proportions of each form. The Nobel announcement says researchers sought methods to create an excess of one form, both to investigate how biological homochirality might arise and to make molecules with the desired properties for use in interactions with living organisms.
Kagan’s 1986 finding showed that chemical reactions could be manipulated to produce a larger imbalance between the mirror forms than previously thought possible. Soai then advanced the work through research described in 1995 and a 2003 reaction that, according to the Academy, produced only one of the two possible mirror images. The prize citation groups their contributions under non-linear effects and autocatalysis in asymmetric organic synthesis—the chemistry of making organic molecules in a way that favors one handed form.
The award was announced on October 7, 2026, by the Royal Swedish Academy of Sciences. The Academy’s press release identifies the two laureates and the shared prize amount; it also points readers to separate popular-science and scientific-background materials for further detail.
“Henri Kagan and Kenso Soai have provided a solution to a chemical mystery that is over a century old: how homochirality can emerge spontaneously.”

Details Beyond the Award Citation
The Academy’s announcement identifies the discoveries and gives a short timeline, but it does not provide detailed reaction conditions, experimental evidence, or a fuller account of how the two researchers’ individual contributions relate to one another. Those details are referred to in the Academy’s separate scientific-background material and are not set out in the press release.
The announcement also does not name specific medicines or quantify how widely the discoveries have been applied in pharmaceutical production. Its account of the 2003 reaction says it formed only one of two possible mirror images; broader claims about the reach of that result should be checked against the scientific background material.

Key Questions
Who won the 2026 Nobel Prize in Chemistry?
Henri B. Kagan and Kenso Soai were named the 2026 chemistry laureates by the Royal Swedish Academy of Sciences on October 7, 2026.
Why did Kagan and Soai receive the prize?
They were recognized for discoveries involving non-linear effects and autocatalysis in asymmetric organic synthesis, which help explain how reactions can favor one of two mirror-image molecular forms.
What is homochirality?
Homochirality is the predominance of one molecular handedness. The Academy notes that living organisms use one of the two mirror-image forms of amino acids in the proteins of cells.
How much prize money will the laureates receive?
The 12 million Swedish kronor prize will be divided equally between Kagan and Soai, according to the Academy.
What remains unknown about the announcement?
The press release does not give detailed experimental conditions, name specific medicines made using the discoveries, or quantify their industrial impact. It directs readers to separate scientific-background materials for more technical information.
