title: Synthesis of (+/-)-sundiversifolide based on Lewis acid-mediated Claisen rearrangement.
abstract: A new and concise synthesis of (+/-)-sundiversifolide (1), an allelopathic bisnor-sesquiterpene lactone isolated from germinating sunflower (Helianthus annuus L.) seeds, was achieved by employing Lewis acid-mediated Claisen rearrangement as the key step.
