Asymmetric organic synthesis and homochirality: a key GS3 Science & Technology topic for pharmaceutical manufacturing.
Why in news
The Royal Swedish Academy of Sciences announced Henri Kagan and Kenso Soai as the 2026 Nobel Prize in Chemistry winners for their work on asymmetric organic synthesis.
Background
Henri Kagan (France, 95) and Kenso Soai (Japan, 76) were awarded the prize. Their research focuses on nonlinear effects and autocatalysis to explain how homochirality emerges spontaneously.
