Abstract
The invention is directed to the preparation of hydroxylated compounds of the vitamin D.sub.2 series and specifically to a process for synthesizing 1.alpha.,25-dihydroxyvitamin D.sub.2, 1.beta.,25-dihydroxyvitamin D.sub.2, their corresponding 5,6-trans isomers and the C-24 epimers of these compounds.
