Chloranthalactones A, B, F, 9-hydroxy heterogorgiolide, and shizukanolide E are a family of natural lindenane-type sesquiterpenoids isolated mainly from chloranthaceae. A general synthetic strategy was accomplished by us for the racemic total syntheses of the five natural products. The key steps included substrate-controlled Matteson epoxidation of ketone and highly diastereoselective intramolecular
