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.

meso-Cyclic imides are monohydrogenated to form the corresponding hydroxy lactams in 88-97% ee using trans-[Ru((R)-BINAP)(H)2((R,R)-dpen)] and related compounds as catalysts with base in THF. The hydrogenation proceeds with high enantiogroup-and chemoselectivity, and it is a desymmetrization reaction, forming up to five stereogenic centers in one reaction. Conversion of a hydroxy lactam into the corresponding iminium ion followed by addition of indene extended the number of stereogenic centers from 5 to 7.
