    摘要： A process for the preparation of a cyclohexane compound of the formula I.
    wherein R represents a hydrogen atom or an alkyl group, an alkylthioalkyl group or an unsubstituted or substituted phenyl group; and R¹ represents an alkyl group, an unsubstituted or substituted benzyl group, a phenethyl group, a phenoxymethyl group, a 2-thienylmethyl group, an alkoxymethyl group or an alkylthiomethyl group; or a salt of said cyclohexane compound (I), which comprises the consecutive steps of cyclizing an acetonylsuccinic acid di-alkyl ester by reaction with a basic reagent ; reacting the resulting compound with an acyl chloride R¹-CO-Cl ; subjecting the resulting compound to a rearrangement reaction in the presence of a catalyst so as to obtain a compound of formula I ; and optionally converting said compound I into a salt thereof. Said process can be carried out in a single reaction vessel without isolation and purification of the intermediate compounds.

    摘要： As new compound is provided a cyclohexane derivative of the formula
    wherein R represents a hydrogen atom or an alkyl group, an alkylthioalkyl group or an unsubstituted or substituted phenyl group; and R' represents an alkyl group, an unsubstituted or substituted benzyl group, a phenethyl group, a phenoxymethyl group, a 2-thienylmethyl group, an alkoxymethyl group or an alkylthiomethyl group, or a salt of said cyclohexane compound.
    This cyclohexane compound exhibits useful plant-growth regulating effects on crop-plants and also non-crop plants such as lawn and may be prepared by cyclization of an acetonylsuccinic acid dialkyl ester, followed by reaction with an organic acid chloride and by intermolecular rearrangement.
