SYNTHESIS OF (24R)-24,25-DIHYDROXYVITAMIN D3

Two versions of the stereoselective synthesis of (24R)-24,25-dihydroxyvitamin D3 were realized.Vitamin D2 and ergosterol were used as starting materials.Methods are proposed for the production of the following key compounds: 6-Methoxy-23,24-bisnor-9,10-seco-3,5-cyclochola-7,10(19)-dien-22-yl phenyl sulfone; 3β-hydroxy-23,24-bisnorchola-5,7-dien-22-yl phenyl sulfone; (2R)-3-methylbutane-1,2,3-triol 1-p-toluenesulfonate.
