Transannular Claisen rearrangement reactions for the synthesis of vinylcyclobutanes: Formal synthesis of (±)-grandisol

Unsaturated eight-membered lactones undergo decarboxylative and non-decarboxylative transannular Ireland-Claisen rearrangement reactions, to give substituted vinylcyclobutanes. A formal synthesis of (±)-grandisol is described. The Royal Society of Chemist
