Two scientists win 2026 Nobel Chemistry Prize for asymmetric synthesis work
In short
The Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Chemistry to French chemist Henri B. Kagan and Japanese chemist Kenso Soai for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis, Chinese outlets reported on October 7. Jiemian said the two will share the 12 million Swedish kronor prize. IT Home said their work explains how the chemical asymmetry of life arose and is important for designing drug production reactions.
Why it matters
The documents present the award as recognition of basic chemistry with practical reach: IT Home said the findings are decisive for chemists designing reactions to make medicines, and that the “Soai reaction” has renewed interest in how life's one-handed chemistry originated. Coverage was limited to the announcement and background, so significance beyond the scientific community is stated only as the outlets frame it.
Key facts
- The 2026 Nobel Prize in Chemistry was awarded to Henri B. Kagan and Kenso Soai, the Royal Swedish Academy of Sciences announced. [ 1 , 2 , 4 , 5 , 6 ]
- The prize recognizes the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis. [ 1 , 4 , 5 , 6 ]
- Caixin reported the announcement was made at 11:45 local time in Stockholm, 17:45 Beijing time, on October 7. [ 4 ]
- IT Home said Kagan, born in France in 1930 and aged 96, found a way to manipulate chemical reactions to create more mirror forms than previously assumed. [ 1 ]
- IT Home said Soai, born in Hiroshima in 1950 and aged 76, designed the first chemical reaction that forms only one of two potential mirror forms, known as the Soai reaction. [ 1 ]
- Jiemian said the laureates will share 12 million Swedish kronor, about 8.02 million to 8.03 million yuan. [ 5 , 6 ]
- Jiemian said Kagan first reported in 1986 the non-linear relationship between catalyst enantiopurity and product enantioselectivity, the “Kagan MLn model”. [ 6 ]
- Jiemian said Soai discovered the first true asymmetric autocatalytic reaction in 1995. [ 6 ]
Confirmed by several sources
- The Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Chemistry to French chemist Henri B. Kagan and Japanese chemist Kenso Soai. [ 1 , 2 , 4 , 5 , 6 ]
- The award is for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis. [ 1 , 4 , 5 , 6 ]
- The award was announced on October 7. [ 1 , 2 , 4 , 5 , 6 ]
Still unclear
- The prize sum and its yuan conversion Only Jiemian, in two separate items from the same outlet, gives the figure and converts it to about 8.02 million yuan in one item and 8.03 million yuan in another; no other outlet in the documents states the amount.
- Kagan's current academic affiliation IT Home lists him at Paris-Sud University in Orsay while Jiemian describes him as an emeritus professor at Université Paris-Saclay; the two accounts differ and neither is corroborated by another outlet.
- The exact wording of the award citation Chinese translations differ slightly between IT Home and Jiemian, and only Caixin gives the English wording, which is a single-source version.
- Xinhua's two reports Xinhua's items carry only headlines with no summary or article text, so their details cannot be checked.
