Mechanochemical Diels-Alder cycloaddition reactions for straightforward synthesis of endo-norbornene derivatives

Under mechanochemical milling conditions, Diels-Alder cycloaddition of cyclopentadiene with maleic anhydride and maleimide derivatives proceeded very smoothly, affording endo-norbornenes exclusively in quantitative yield. All the transformations were accomplished at room temperature without using any catalyst or organic solvent, thus the workup and purification procedure is very simple. Control experiments on traditional and other tentative conditions were also investigated. Georg Thieme Verlag Stuttgart - New York.
