Olefin Metathesis in Organic Synthesis. Intramolecular metathesis of a diene to form a cyclic olefin Ring Closing Metathesis (RCM) M M M. Mechanism of Ring Closing Metathesis. The key intermediate is a metallacyclobutane, which can undergo cycloreversion either towards products or back to starting. The intermolecular process is called Cross-Enyne Metathesis, whereas intramolecular reactions are referred as Ring-Closing Enyne Metathesis. Development of a General, Sequential, Ring-Closing Metathesis/Intramolecular Cross-Coupling Reaction for the Synthesis of Polyunsaturated Macrolactones.

Ring closing enyne metathesis: A powerful tool for the synthesis of heterocycles He´le`ne Villar,ab Marcus Fringsa and Carsten Bolm*a Received 2nd August 2006. Ring-closing metathesis to encounter each other is inversely proportional to the ring size, the necessary intramolecular cycloaddition becomes increasingly. Ring-closing metathesis is a variant of the olefin metathesis reaction in which alkylidene moieties. While some of these have intramolecular, ring-closing. Using a tandem Morita–Baylis–Hillman (MBH) and ring-closing-metathesis (RCM) sequence, an alternative high yielding method for the construction of intramolecular.
