Abstract: 1&agr;,24(S)-Dihydroxy vitamin D2 which is useful as an active compound of pharmaceutical compositions for the treatment of disorders of calcium metabolism and for various skin disorders. The invention also includes preparation of synthetic 1&agr;,24(S)-dihydroxy vitamin D2 starting from ergosterol which is converted in six steps to 24-hydroxyergosterol. 24-Hydroxyergosterol is irradiated and thermally converted to 24-hydroxy vitamin D2 which is converted in six steps to 1&agr;,24(S)-dihydroxy vitamin D2. The syntheses also produced novel intermediates.
