The invention relates to a method for synthesizing a 1R,2R,3R-substituted cyclopentanone compound. The method comprises: carrying out a reaction on a compound 1 and a halogenated alkane in an organicsolvent under the actions of a strong alkali and a cuprous salt to obtain a compound 3, carrying out ester hydrolysis on the compound 3 under the action of an alkali or pancreatin, and carrying out deprotection by using a fluorine reagent to obtain the product. According to the present invention, the synthesis method has characteristics of high yield, high product purity, good diastereoselectivity, easy reaction control and simple post-treatment, is suitable for industrial production, and can synthesize high-purity and high-yield alprostadil, lubiprostone, and the analogs of misoprostol and limaprost. The compound 1 is defined in the specification.
