1,23-Dihydroxyvitamin D compounds
 This invention provides novel 1,23-dihydroxyvitamin D compounds, a process for preparing such compounds of novel intermediates in such process. As indicated by its binding affinity for the 1.alpha.,25-dihydroxyvitamin D.sub.3 receptor protein, the compounds of this invention would function as effective substitutes for vitamin D and certain vitamin D metabolites for the regulation of calcium and phosphorous metabolism and for treatment of bone-related diseases.
