Content: Diels-Alder Reaction is found by both Germany chemists O. Diels and his assistant, K.Alder, in 1982. The reaction between diene and dienophile with double bonds or tri-bonds became into the hexahydroxy compounds. Because of good regio- and stereoselectivity, Diels-Alder reaction has become an important tool of synthetic chemistry and a significant subject of theoretical study.
However, concerning the opinion of the stereoselectivity of the Diels-Alder reaction, there is no uniform met...
