The adduct was also demonstrated to always be a six-membered ring, with addition taken place between the double bond of the dienophiles and the carbon atoms of the one and four positions in the diene. In the 1890’s, Alder began to study the general experimental properties of the diene synthesis and the overall concept of the method for synthetic purposes. Kurt Alder was an able stereo chemist and showed how a diene addition took place at double bounds with a cis configuration. Alder showed that the reaction was equally general with respect to the dienophiles, given that the double bond was appropriately activated by nearby carbonyl, cyano, or carboxyl groups. The unsaturated compounds that did not have properly placed activating groups failed to result in
