Nobel Prize In Chemistry 2026: Henri B. Kagan, Kenso Soai Win For Breakthroughs In Asymmetric Synthesis

The Royal Swedish Academy of Sciences has awarded the 2026 Nobel Prize in Chemistry to Henri B. Kagan and Kenso Soai for discoveries that transformed asymmetric organic synthesis.

Kagan, Soai Recognised For Chemical Breakthrough

The laureates were honoured “for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis”, the Royal Swedish Academy of Sciences announced.

Their work has given chemists new ways to control chemical reactions and understand how molecules with different mirror-image forms are produced.

According to the Nobel Prize announcement, the discoveries have also helped address one of chemistry’s longstanding questions: how homochirality, a characteristic found in all living organisms, can arise.

Soai Reaction And The Origins Of Life

Kenso Soai developed what became known as the Soai reaction, a landmark reaction in which only one of two potential mirror-image forms of a molecule is produced.

“Kenso Soai – awarded the 2026 Nobel Prize in Chemistry – designed the first chemical reaction in which only one of the potential mirror images was formed,” the post said.

The academy described the Soai reaction as “one of the most spectacular chemical experiments ever conducted”, noting that, apart from life itself, no one had previously achieved such a feat.

The reaction has renewed interest in the chemical origins of life. Researchers around the world are now attempting to replicate Soai’s achievement with the aim of producing homochiral amino acids and sugars.

Kagan’s Discovery Changed Reaction Design

Henri B. Kagan was recognised for discovering non-linear effects in chemical reactions, giving chemists a new way to understand and manipulate how reactions proceed.

The Nobel Prize said Kagan’s discovery allows chemists to create a greater excess of one molecular mirror image than had previously been considered possible.

“The non-linear effects that fellow laureate Henri B. Kagan discovered have become an important tool for chemists when they design new reactions,” the academy said.

The behaviour of a reaction can reveal information about its mechanism. Chemists can use that information to optimise reactions and produce purer enantiomers.

Scientists Solve A Century-Old Mystery Of Homochirality

Last year, the Nobel Prize in Chemistry was awarded to three scientists for developing new molecular structures capable of trapping vast quantities of gas. The breakthrough laid the groundwork for technologies that could potentially remove greenhouse gases from the atmosphere and extract moisture from desert environments, the Associated Press reported.

Heiner Linke, chair of the Nobel Committee for Chemistry, said Henri B. Kagan and Kenso Soai had helped solve a chemical mystery that had puzzled scientists for more than a century.

Linke said Henri Kagan and Kenso Soai had helped solve a more than century-old chemical mystery of how homochirality could emerge spontaneously, describing the reactions they developed as spectacular.
