Conventionally, cholester-1,4,6-triene -3- has been used as an intermediate for the production of various active vitamin D3.
One, 25-hydroxycholester-1,4,6-trien-3-one, 24,25-dihydroxycholester-1,4,6-trien-3-one, and the like are known. The present inventors discovered a compound that has not been published in the literature25
-Hydroxy-3,24-dioxocholester-1,
4,6-trienes are also active vitamins.
We conducted extensive research using the novel compound 3β,25-dihydroxy-24-oxocholest-5 - ene, which the present inventors had previously proposed (Japanese Patent Application No. 15420/1984), which we believed to be useful as an intermediate for the production of D3. As a result, although it is a compound that easily causes side reactions because it has an oxo group and a hydroxyl group in its side chain,
Surprisingly, by reacting such 3β,25-dihydroxy-24-oxocholest-5-enes with 2,3-dichloro-5,6-dicyanobenzoquinone in an inert solvent, a side reaction occurs. The present invention was achieved by discovering the fact that 25-hydroxy-3,24-dioxocholester-1,4,6-trienes can be easily obtained without any oxidation, and that such compounds can serve as intermediates for active vitamin D3 . It is.
