摘要：
A process for the production of a cyclopentenol compound represented by the formula I: ##STR1## wherein R.sub.1 represents a 2-propenyl group or a 2-propynyl group from a cyclopentenolone compound represented by the formula II: ##STR2## by protecting the hydroxyl group of the compound II, reacting the protected compound II with a reagent system obtained from TiCl.sub.4, Zn and CH.sub.2 Br.sub.2 or CH.sub.2 I.sub.2 and removing the protecting group from the resulting reaction product.
