    摘要： Described are novel compounds of the formula (IV)
    wherein R 1 is a hydrogen atom, a nyaroxyl group or a protected hydroxyl group and R 2 is a hydrogen atom or a protecting group,

    a pharmaceutical composition useful as a cell differentiation-inducing agent, which contains an effective amount of a compound of the formula IV (wherein R 2 is H) as an active ingredient and a pharmaceutically acceptable carrier or diluent,
    a method of inducing cell differentiation by administering an effectiveamount of a compound of the formula IV (wherein R 2 is H to a patient,
    and a proceesfor producing a compound of the formula (IV) by subjecting a previtamin D 3 derivative of the formula (III)

    wherein R 1 and R 2 are as defined above, to thermal isomerization to yield a vitamin D 3 derivative of the formula (IV) mentioned above.

    摘要： There are disclosed novel derivatives of 26,26,26,27,27,27-hexafluorovitamin D₃ having a fluorine atom at the 23- and/or 24-position which have an excellent pharmacological activity and a process for production thereof. The novel compounds are represented by the general formula (1).
    wherein R₁ʹ denotes a hydrogen atom, a hydroxyl group or a protected hydroxyl group, R₂ denotes a hydrogen atom or a protecting group for a hydroxyl group, R₃ denotes a hydrogen atom, a fluorine atom, a hydroxyl group or a protected hydroxyl group and R₄ and R₄ʹ each denotes a hydrogen atom, or one of them denotes a hydrogen atom and the other denotes a fluorine atom, hydroxyl group or a protected hydroxyl group or R₄ and R₄ are combined to denote an oxo group, with a proviso that at least one of R₃, R₄ and R₄ʹ denotes a fluorine atom. The process for production thereof comprises subjecting a compound represented by the general formula (3)
    wherein R₁ʹ, R₂, R₃, R₄ and R₄ʹ are the same as defined above, to thermal isomerization and optionally further to a deprotection reaction.
