Synthesis and Determination of the Configuration of 23,25-Dihydroxyvitamin D3; a New Metabolite of Vitamin D3; X-Ray Crystal Structure of a 3,23,25-Triol Precursor

The configuration at the C-23 position of 23,25-dihydroxyvitamin D3, a new metabolite of vitamin D3, was determined as S by comparison with the synthetically prepared C-23 S- and R-isomers and an X-ray crystallographic determination of the structure of the 3,23,25-triol (7b).
