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.
一种用于生产由化学式I表示的环戊醇化合物的方法:其中R.sub.1代表由化学式II表示的环戊醇酮化合物的2-丙烯基团或2-丙炔基团,该方法包括保护化合物II的羟基,将保护的化合物II与从TiCl.sub.4,Zn和CH.sub.2 Br.sub.2或CH.sub.2 I.sub.2获得的试剂体系反应,并从所得的反应产物中去除保护基。
