    Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently producing at a low cost a norbornene derivative having a spiro skeleton or a cyclic hydrocarbon compound that may be used as a raw material for synthesizing a norbornene derivative having a spiro skeleton. SOLUTION: A compound represented by formula (1) and a compound represented by formula (2-1) or the like are subjected to condensation reaction in a hydrocarbon solvent in the presence of an alkali metal hydroxide as a base, to produce a compound represented by formula (3-1) or the like, wherein, in formula (1) and (4), R 1 to R 8 indicate each a hydrogen atom, a halogen atom or the like; A indicates a single bond, a divalent (substituted) hydrocarbon group or the like; and a, b and c indicate each 0 to 2; and in formula (2-2), R 9 and R 10 indicate a carbocycle, a heterocycle or the like bonded with each other; and X and Y each indicate a halogen atom, a sulfonate group or the like.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for economically and efficiently producing a spiro compound.
    SOLUTION: The spiro compound represented by formula (4) is produced by condensing cyclization reaction of a compound represented by formula (1) with a compound represented by formula (2-1) in the presence of a base, wherein a metal hydride is used as the base. [In formula (1) and formula (4), R
    1 to R
    8 are each H, a halogen or the like; A is a single bond, a divalent (substituted) hydrocarbon or the like; and (a), (b) and (c) are 0 to 2. In formula (2-1), R
    9 and R
    10 are each a carbocyclic ring, a heterocycle or the like, which are mutually bonded; and X and Y are each H, a halogen, a phosphate or the like].
