  Kurt Alder Biography | World of Chemistry
Kurt Alder was recognized for his contribution to synthetic organic chemistry, especially for the reaction which has been called the diene reaction, or the Diels-Alder reaction, after Alder and his mentor-colleague, Otto Diels.
Kurt attended the local schools, but at the end of World War I, the region in which the Alders lived became part of Poland, and Joseph Alder moved his family to Kiel in order to retain their German citizenship.
Alder and his students carried out extensive investigations on the geometry of the ring formation, and discovered regularities which allowed the geometry to be predicted with certainty.

 Kurt Alder - Biography
Kurt Alder was born in Königshütte, Upper Silesia, on the 10th of July 1902.
As early as 1927-1928, whilst at Kiel, Alder had studied problems of systematic organic chemistry in collaboration with his teacher O. Diels, and this lead to their joint discovery of the principle of the diene-synthesis, which they investigated and determined in all its aspects.
Kurt Alder's investigations have been described in about 150 papers, which were published mainly in Justus Liebig's Annalen der Chemie, in the Berichte der Deutschen Chemischen Gesellschaft and in Angewandte Chemie.

 Kurt Alder - Wikipedia, the free encyclopedia
Kurt Alder (10 July 1902 20 June 1958) was a German chemist who won the Nobel Prize in Chemistry jointly with Otto Paul Hermann Diels in 1950.
Alder was born in the industrial area of Königshütte in Upper Silesia, where he received his early schooling.
Forced to leave the area for political reasons (that part of Germany became a part of Poland) after the First World War, he studied chemistry at the University of Berlin from 1922, and later at the University of Kiel where his PhD was awarded in 1926 for work supervised by Diels.

In 1928, two German Chemists by the names of Otto Diels and Kurt Alder discovered that butadiene reacts vigorously with maleic anhydride to give cis-1, 2, 3, 6-tetrahydrophthalic andhydride.
An inert solvent such as ether or benzene is used to carry out the reaction, and typically the diene and dienophile are mixed in equimolar proportions at STP1.

 Diels - Alder Tutorial
The Diels - Alder reaction is named after Otto Diels and Kurt Alder.
The Diels - Alder reaction is a cycloaddtion reaction between a two conjugated double bonds (a diene) and a carbon carbon double bond or triple bond (dienophile).
The reaction is very important because two new carbon-carbon bonds and a cyclohexene ring are formed in a single step.

 Diels-Alder Mechanism
The three double bonds in the two starting materials are converted into two new single bonds and one new double bond.
Since this reaction forms two new carbon-carbon bonds in a single step, it is a very useful and powerful reaction (one which earned Otto Diels and Kurt Alder a Nobel prize in chemistry for discovering it).
Typically, the Diels-Alder reaction works best when either the diene is substituted with electron donating groups (like -OR, -NR etc) or when the dienophile is substituted with electron-withdrawing groups (like -NO, -CN, -COR, etc).
