    摘要： A process for the production of a cyclopentenol compound represented by the formula I:

    wherein R₁ represents a 2-propenyl group or a 2-propynyl group, which comprises the steps of;

    (i) protecting the hydroxyl group of the cyclopentenolone compound II:
    wherein R₁ is the same as defined above to give a cyclopentenolone derivative represented by the formula III:
    wherein R₁ is the same as defined above and A is a protecting group for a hydroxyl group;
    (ii) reacting a mixture of zinc and dibromomethane or diiodomethane in an inert organic solvent with titanium tetrachloride;
    (iii) reacting the resulting reaction mixture with a cyclopentenolone derivative III to give a cyclopentenol derivative IV:
    wherein R₁ and A are the same as defined above; and
    (iv) removing the protecting group A from the cyclopentenol derivative represented by the formula IV to give the cyclopentenol compound I.
