An improved process for preparing an optically active 4-hydroxycyclopentenone of the formula: ##STR1## wherein R is a lower alkyl, the symbol means 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 medicinal or agricultural products, particularly pharmaceutically active prostaglandins, and intermediates for preparing the optically active and/or racemic 4-hydroxycyclopentenone.
一种改进的制备光学活性4-羟基环戊烯酮的方法,其公式为:##STR1## 其中R是低级烷基,该符号表示双键或三键,标记*的碳是不对称碳,以及相应的外消旋4-羟基环戊烯酮,它们作为制备药物或农业产品,特别是药物活性前列腺素的中间体,以及用于制备光学活性及/或外消旋4-羟基环戊烯酮的中间体是有用的。
