Detailed explanation-1: -Benjamin List, (born January 11, 1968, Frankfurt am Main, West Germany [now in Germany]), German chemist who was awarded the 2021 Nobel Prize for Chemistry for his work on asymmetric organocatalysis. He shared the prize with British chemist David MacMillan.

Detailed explanation-2: -Benjamin List and David MacMillan are awarded the Nobel Prize in Chemistry 2021 for their development of a new and ingenious tool for molecule building: organocatalysis. Its uses include research into new pharmaceuticals and it has also helped make chemistry greener.

Detailed explanation-3: -Bertozzi of Stanford University, Morten Meldal of the University of Copenhagen, and K. Barry Sharpless of the Scripps Research Institute were awarded the prize “for the development of click chemistry and bioorthogonal chemistry.” Both Bertozzi and Sharpless share roots at MIT and the greater Boston area.

Detailed explanation-4: -Barry Sharpless – who is now being awarded his second Nobel Prize in Chemistry – started the ball rolling. Around the year 2000, he coined the concept of click chemistry, which is a form of simple and reliable chemistry, where reactions occur quickly and unwanted by-products are avoided.

Detailed explanation-5: -In 2000, Benjamin List and David MacMillan, independent of each other, developed a new type of catalysis that builds upon small organic molecules. An important capacity of many such catalysts is the ability to build only one of two mirror image variants of a molecule.
