The stereoselective synthesis of substituted piperidines by a ruthenium-catalyzed ring rearrangement of cyclopentene derivatives is demonstrated. The influence of different substituents and the effect of ethylene on the metathesis reaction is described. The ring rearrangement can be combined with a molybdenum-catalyzed crossmetathesis reaction using allyltrimethyl silane as coupling partner. The first
