Cyclohexanetriol derivatives represented by the formula
wherein
R¹, R² and R³ are the same or different, and each denotes a hydrogen atom or a protecting group of a hydroxyl group,
X denotes an oxygen atom, =CHCH₂OR⁴, =CHCHO or =CHCO₂R⁵, Y denotes a hydrogen atom and Z denotes -OR⁶, or Y and Z together form a single bond; or X and Z together form =NO-, =CHCH(OR⁷)O-or =CHCO₂- and Y is a hydrogen atom, R⁴ and R⁶ denote a hydrogen atom or a protecting group of a hydroxyl group respectively, R⁵ denotes a lower alkyl group, and R⁷ denotes a hydrogen atom or a lower alkyl group.
Said derivatives are useful as synthetic intermediates of 1 -hydroxyvitamin D derivatives.
