Abstract
NEW MATERIAL:(24R)-24, 25-Dihydroxy-5,6-trans-vitamin D3.
USE: Effective for calcium dysbolism of a nephrectomized animal, etc. and advantageous over the well-knwon compound due to no trouble in preparation.
PROCESS: (24R)-24, 25-Dihydroxyvitamin D3 is brought into contact with iodine in an inert solvent and isomerized to give the titled compound. A hydrocarbon solvent, e.g. hexane or pentane, is preferably used as the inert solvent, and the amount of the iodine varies with the amount of the raw material and the reaction conditions. The iodine is removed from the reaction mixture by the conventional method, and the reaction mixture is extracted and subjected to the high speed chromatography to isolate the titled compound.
