A novelsynthesis of (± )-Vernolepin (1) is described. A suitably substituted cis-fused 2-oxa-3-decalone precursor (29) has been constructed starting from 2,5-cyclohexadiene carboxylic acid via an intramolecular cyclopropanationreaction (23 to 18). The route culminated in the synthesis of Grieco's lactone (53) which has previously been converted to (± )-vernolepin (1) and (± )-vernomenin (2).
