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).
提供了一种由下列通用式[I]表示的新型(1R,2S)-1-酰基-2-羧基环己-4-烯衍生物及其制备方法:##STR1##(其中,R1代表氢原子、低碳基、取代或未取代的芳基;R2代表氢原子或低碳基)。还提供了一种制备下列通用式[A]所表示的(3S,4R)-4-取代-3-羧基环戊酮衍生物的方法:##STR2##(其中,R1和R2与上述相同)。
