  An improved process for preparing an optically active 4-hydroxycyclopentenone of the formula: wherein R is a lower alkyl, the symbol = means a double bond or triple bond, and the * marked carbon is an asymmetric carbon, and the corresponding racemic 4-hydroxycyclopentenone, which are useful as an intermediate for preparing medical or agricultural products, particularly pharmaceutically active prostaglandins, and intermediates for preparing the optically active and/or racemic 4-hydroxycyclopentenone.

  一种制备具有光学活性的式 4-羟基环戊烯酮的改进工艺： 其中 R 为低级烷基，符号 = 表示双键或三键，标记为 * 的碳为不对称碳，以及相应的外消旋 4-羟基环戊烯酮，可用作制备医药或农产品，特别是具有药用活性的前列腺素的中间体，以及制备光学活性和/或外消旋 4-羟基环戊烯酮的中间体。

  The present invention relates to a process for the preparation of dicarboxylic acids or dicarboxylic acid esters comprising the following process steps: A1 provision of at least the following reactants: a1 - a first aliphatic compound having 5 to 40 carbon atoms with in each case at least one functional group of the general formula (I) and (II), wherein R1 is a saturated or unsaturated aliphatic group having 2 to 20, preferably 4 to 16 and particularly preferably 6 to 12 carbon atoms and R2 is a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, preferably having 1 to 5 carbon atoms and particularly preferably having 1, 2 or 3 carbon atoms formula (I) and (II) and a2 at least one further aliphatic compound which differs from the first aliphatic compound, chosen from the group consisting of a2a a compound of the general formula (III) in which n is chosen from 1, 2, 3, 4 and 5; a2b a compound of the general formula (IV) in which R3 is a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, preferably having 1 to 5 carbon atoms and particularly preferably having 1, 2 or 3 carbon atoms and R4 and R5 independently of each other are a saturated alkylene group having 1 to 14 carbon atoms, preferably having 1 to 10 carbon atoms and very particularly preferably 1 to 5 carbon atoms; A2 provision of at least one organometallic catalyst based on ruthenium; A3 bringing into contact of the reactants and the catalyst to obtain a product mixture and the catalyst; A4 separating off of the catalyst; A5 optionally division of the product mixture into products Pi, i being a natural number, and the reactants which remain; the process being a metathesis reaction, and the dicarboxylic acid obtainable therefrom and the dicarboxylic acid ester obtainable therefrom, a process for the preparation of a polymer and the polymer obtainable by this process.
