摘要
Comprehensive Summary(±)-Atrachinenins A—C(1—3),three meroterpenoids possessing novel C_(27) skeletons,were isolated from the rhizomes of Atractylodes chinensis.(±)-Atrachinenin A(1)possesses an unprecedented cage-like skeleton with a fused 6/6/5/5 tetracyclic system(decahy-dro-1,5:4a,7-dimethanobenzo[7]annulene),which may be formed by the intermolecular cyclization of(±)-atrachinenin C(3).
