In 1950 he was awarded (with Kurt Alder, his student) the Nobel Prize in Chemistry "for their discovery and development of the diene synthesis," known also as the Diels-Alder Reaction. This amazing reaction regioselectively produces up to four chiral centers and is widely considered to be one of the most powerful reactions in organic synthesis.
