Kagan and Soai awarded 2026 Nobel Prize in Chemistry

Henri B Kagan of France and Kenso Soai of Japan have been recognized with the 2026 Nobel Prize in Chemistry for their contributions to understanding asymmetric synthesis—the process by which chemical reactions can generate molecules with specific handedness, or chirality.

Chirality is a fundamental property of molecules whereby they exist in mirror-image forms, similar to left and right hands. The ability to selectively produce one form over another has profound implications across pharmaceuticals, agrochemicals, and materials science, as different chiral forms of the same molecule can have vastly different biological effects.

The laureates' discoveries have provided critical insights into the mechanisms underlying these reactions and have enabled chemists to develop more efficient and selective methods for synthesizing desired molecular forms. Their work has had lasting influence on both academic research and industrial chemical production.

The Nobel Prize in Chemistry, awarded annually by the Royal Swedish Academy of Sciences, recognizes outstanding scientific achievements in the field. The prize underscores the importance of fundamental research in asymmetric synthesis and its applications in developing new medicines and materials that benefit society.
