摘要：

Alkene metathesis has become a synthetic method that has strongly modified approaches in the building of complex molecules. The review will concentrate on the recent applications of ring-closing metathesis (RCM) and crossmetathesis (CM) reactions for the design of useful molecules and architectures: new functional macrocycles (RCM) and multifunctional linear alkenes (CM), but also cyclic ligands, rotaxanes, catenanes, and supramolecular systems.
