<p>The present invention relates to processes for epimerising alcohols of compounds having a hydroxyl substituent on an asymmetric allylic carbon, such as compounds useful for the synthesis of vitamin D analogues where the epimeric hydroxyl substituent is at the 24 position. The Invention further relates to methods of producing intermediates useful for the synthesis of calcipotriol by said epimerisation processes.</p> |
