    • PROBLEM TO BE SOLVED: To provide a method for readily obtaining γ-thujaplicin useful as a pharmaceutical drug intermediate at a low cost in a high yield.
      SOLUTION: The method for producing γ-thujaplicin comprises: (1) a first step of reacting cyclopentadiene with sodium amide in an N, N-dimethylformamide solvent so as to prepare sodium cyclopentadienylide and reacting the same with an isopropylating agent so as to obtain an isopropyl cyclopentadiene mixture; (2) a second step of reacting the isopropyl cyclopentadiene mixture with dichloroketene so as to obtain a 7,7-dichlorobicyclo[3.2.0]-hepto-2-en-6-one derivative mixture; and (3) a third step of subjecting the 7,7-dichlorobicyclo[3.2.0]-hepto-2-en-6-one derivative mixture to solvolysis under a basic condition so as to obtain a crude product and isolating γ-thujaplicin from the same by crystallization.
