Preparation method of 25-hydroxyvitamin D3, 1alpha, 25-dihydroxyvitamin D3 and isotope internal standard compound thereof

The invention discloses a preparation method of 25-hydroxyvitamin D3 and 1alpha, 25-dihydroxyvitamin D3 and an isotope internal standard compound thereof. The preparation method comprises the following steps: a compound III is subjected to SO2 conjugate protection, O3 oxidation, NaBH4 reduction, iodination ring opening, conjugate addition with acrylate, and reaction with a methyl Grignard reagentor isotope labeled methyl Grignard reagent, a silicon protecting group is removed under the action of TBAF, and a product is obtained through ultraviolet irradiation configuration inversion under thecatalysis of 9-acetyl anthracene. The method is good in reaction selectivity, high in total yield, simple and convenient to operate and short in isotope introduction step, and the isotope utilizationrate is greatly increased.
