Interpretation: The product formed from the ring-closing metathesis of given compound is to be drawn, and the synthesis of metathesis starting material using
Concept introduction: The ring-closing metathesis (RCM) by Grubbs catalyst occurs, when the starting material is diene. This reaction is facilitated under high-dilution condition as it favors intramolecular metathesis instead of intermolecular metathesis.
Answer to Problem 26.48P
