Otto Paul Hermann Diels (1876-1954) was born In Hamburg, Germany, and received his Ph.D. at the University of Berlin working with Emil Fischer. He was professor of chemistry both at the University of Berlin (1906-1916) and at Kiel (1916-1948). His most important discovery was the so-called Diels-Alder reaction, which he developed with one of his research students and for which he received the 1950 Nobel Prize in chemistry. 

Otto Paul Hermann Diels (1876-1954) was bom in Germany, the son of a professor of classical philology at the University of Berlin. He received a Ph.D. from that university, working with Emil Fischer. Diels was a professor of chemistry at the University of Berlin and later at the University of Kiel. Two of his sons died in World War II. He retired in 1945 after his home and laboratory were destroyed in bombing raids. He received the 1950 Nobel Prize in chemistry, sharing it with his former student Kurt Alder.

The Diels-Alder reaction, like many reactions in organic chemistry, is named after the chemists who discovered it—in this case Otto Paul Hermann Diels (1876-1954) and Kurt Alder (1902-1958). Kurt Alder was actually Diels student at the University of Kiel, and Alder was awarded a PhD in 1926. Alder and his advisor Diels jointly received the Nobel Prize in Chemistry in 1950. 

First discovered by Otto Paul Hermann Diels and Kurt Alder in 1928, the Diels-Alder reaction involves the cycloaddition of a conjugated diene with substituted alkene (dienophile) to yield a substituted cyclohexene product. These products can be further used in the synthesis of natural products. A lesser-known reaction is the hetero-Diels-Alder (HDA) reaction. In 1974, Danishefsl et al. developed a diene that can easily produce dihydro-pyranones. ° Since then, much research has been performed with Danishefksy s diene in order to develop new Lewis-acid catalysts for Diels-Alder reactions. 

Nearly 90 years ago, in 1928, Professor Otto Paul Hermann Diels and his student Kurt Alder were the first to properly identify the products of the reaction of cyclopentadiene with quinone [69]. The principal of this chemical transformation, known today as the Diels-Alder reaction, has foimd tremendous application in the total synthesis of complex natural products and is rightfully considered one of the most important carbon-carbon bond forming reactions in organic chemistry [70]. 

Otto Paul Hermann Diels (1876-1954) Diels obtained his Ph.D. in 1899 while studying with Emil Fischer at the University of Berlin. He later became Associate Professor of Chemistry at the University of Berlin, and in 1916 he moved to the University of Kiel. In 1906 Diels discovered carbon suboxide gas (C3O2), obtained from the dehydration of malonic acid. He did extensive studies on saturated fats and fatty acids. Diels also developed the use of selenium as a mild dehydrogenation agent. This latter work led to the commercial production of polyunsaturated oils. 

This famous class of reactions are named for Otto Paul Hermann Diels and Kurt Alder, who were primarily responsible for its development. Diels and Alder received the Nobel Prize in 1950 for this work. See Experiment [14] for a biography of Diels. A short biography of his student Kurt Alder follows. ...

Otto Paul Hermann Diels and Kurt Alder first documented the novel reaction in 1928, for which they were awarded the Nobel Prize in Chemistry in 1950. The Diels-Alder reaction is generally considered one of the more useful reactions in organic chemistry since it requires very little energy to create a cyclohexene ring, which is useful in many other organic reactions. 

Diels-Alder reaction [1, 2] (Fig. 2.4) happens between conjugated dienes and double bond substrates to form substimted cyclohexene system. Even if the atoms in some positions are non-carbon heteroatoms, the reaction still can occur normally. The reaction was first discovered by Otto Paul Hermann Diels and Kurt Alder in 1928. They won the 1950 Nobel Prize for chemistry because of this discovery.
