<Robert H. Grubbs> coauthored template-directed <ring-closing metathesis> research. Coordination to a template can bring reactive ends of a polyether-containing chain into an arrangement favourable for ring formation.
This connects catalysis with molecular preorganization: a template changes the accessible geometry, while a metathesis catalyst carries out bond reorganization.<Template-Directed Ring-Closing Metathesis: Synthesis and Polymerization of Unsaturated Crown Ether Analogs by Michael J. Marsella and others>[Lithium-templated formation of unsaturated crown-ether analogues]{ref}
