In order to provide a novel method for producing a cyclopentanone compound, the present invention is a method for producing a cyclopentanone compound represented by the formula (I). The method includes the steps of: substituting the group represented by Y by a hydrogen atom by allowing a compound represented by the formula (III) or an intermediate compound obtained from the compound represented by the formula (III) to react with a catalyst or a halogenating agent; and substituting, by hydrogen atoms, (i) the group or the atom represented by Z

, by reducing the compound represented by the formula (III) or the intermediate compound obtained from the compound represented by the formula (III).
为了提供一种新颖的环戊酮化合物生产方法,本发明提供了一种生产由式(I)表示的环戊酮化合物的方法。该方法包括以下步骤:通过让式(III)表示的化合物或由式(III)表示的化合物得到的中间体与催化剂或卤化剂反应,将由Y表示的基团取代为氢原子;通过还原式(III)表示的化合物或由式(III)表示的化合物得到的中间体,将(i)由Z1表示的基团或原子和(ii)由Z2表示的基团或原子取代为氢原子。
