WebRing-closing metathesis has become an essential tool for C-C bond formation as demonstrated by the profound impact on total synthesis in recent years. 1 The first examples date back to 1980 and involved the use of tungsten-based catalysts for the preparation of macrocycles from dialkenyl keto-esters and dialkenyl ketones (Villemin and Tsuji, … WebRing Closing Metathesis (RCM) The Ring-Closing Metathesis (RCM) allows synthesis of 5- up to 30-membered cyclic alkenes. The E/Z -selectivity depends on the ring strain. The Ru-catalysts used tolerate a variety of functional groups, but normally the molecule must have polar side chains that are able to build a template for the catalyst.
