Provided is a novel (1R, 2S)-1-acyl-2-carboxycyclohex-4-ene derivative represented by the following general formula [I], and its producing method, ##STR1## (where R.sup.1 represents a hydrogen atom, a lower alkyl group, or substituted or unsubstituted aryl group, and R.sup.2 represents a hydrogen atom, or a lower alkyl group). Also provided is a method of producing a (3S, 4R)-4-substituted-3-carboxycyclopentanone derivative represented by the following general formula [A], ##STR2## (where R.sup.1 and R.sup.2 are the same as those mentioned above).
提供的是一种由以下通用公式[I]表示的新颖的(1R, 2S)-1-酰基-2-羧基环己-4-烯衍生物,以及其生产方法,其中R.sup.1代表氢原子、较低的烷基基团或取代或未取代的芳基基团,R.sup.2代表氢原子或较低的烷基基团。还提供了一种生产由以下通用公式[A]表示的(3S, 4R)-4-取代-3-羧基环戊酮衍生物的方法,其中R.sup.1和R.sup.2与上述相同。
