“…Although the [4+2] cycloaddition reaction now bears the names of Professor Otto Diels and his student Kurt Alder for their seminal publication in 1928,1 history could easily have turned out otherwise. Indeed, in the two decades preceding their work, some of the greatest organic chemists of the day, including Thiele, Zincke,2 and von Euler,3 had already unknowingly observed the reaction 4. The reaction studied by Diels and Alder was that between cyclopentadiene and benzoquinone, giving a mixture of mono‐ and di‐adducts ( 1 and 2 ), and it was the successful identification of the products, the formation of which was inexplicable with the chemistry known at the time, that ensured them a place in history (Scheme ).…”

“…In fact, Walther Albrecht (a student of Johannes Thiele) had performed the same reaction as that shown in Scheme some two decades previously, but had misassigned the structures of the products and thus missed the significance of the chemistry he had performed 12. Hans von Euler, who later won the Nobel Prize in Chemistry for his work on enzymes, had also witnessed the similar formation of a double adduct of isoprene with benzoquinone some years earlier, but despite assigning the structure of this compound correctly,3 had been too busy with other projects to follow up on this remarkable result.…”

“…Die [4+2]‐Cycloaddition trägt wegen ihrer bahnbrechenden Veröffentlichung 1928 jetzt die Namen des Professors Otto Diels und seines Studenten Kurt Alder,1 die Geschichte hätte aber auch anders verlaufen können. In den vorausgehenden zwei Jahrzehnten hatten einige der bedeutendsten Organiker dieser Zeit, wie Thiele, Zincke2 und von Euler,3 diese Reaktion bereits beobachtet, ohne es zu wissen 4. Die von Diels und Alder untersuchte Reaktion war die zwischen Cyclopentadien und Benzochinon, die ein Gemisch aus Mono‐ und Diaddukten ( 1 und 2 ) lieferte.…”

“…Hans von Euler, dem später der Nobelpreis für Chemie für seine Arbeiten zu Enzymen verliehen wurde, beobachtete ebenfalls einige Jahre früher die ähnliche Bildung eines Doppeladdukts von Isopren mit Benzochinon. Er erkannte die Struktur dieser Verbindung richtig,3 doch er war zu beschäftigt mit anderen Projekten, um dieses bemerkenswerte Ergebnis weiter zu verfolgen.…”
