Abstract
Ring-closing metathesis of unsaturated carboxylic acids vinyl esters enables an efficient synthesis of endocyclic enol lactones. The developed methodology offers an easy route for synthetically challenging target molecules with different functional groups and substitution. Vinyl esters of cyclic carboxylic acids can also be successfully applied for domino ring-opening ring-closing metathesis sequences.
