A lab mistake at Cambridge reveals a powerful new way to modify drug molecules

Cambridge scientists have discovered a light-powered chemical reaction that lets researchers modify complex drug molecules at the final stages of development. Unlike traditional methods that rely on toxic chemicals and harsh conditions, the new approach uses an LED lamp to create essential carbon–carbon bonds under mild conditions. This could make drug discovery faster and more environmentally friendly. The breakthrough was uncovered unexpectedly during a failed laboratory experiment. The study, published on March 12 in Nature Synthesis, introduces what the team calls an "anti-Friedel-Crafts" reaction. Traditional Friedel-Crafts chemistry requires powerful chemicals or metal catalysts and harsh laboratory conditions. Because of th... [9929 chars]
