摘要:
A process for producing 3β, 14β-dihydroxyethianaldehyde is disclosed wherein the oxidation of the lactone ring of digitoxigenin-3-acetate is conducted with an alkaline periodate in the presence of a catalytic amount of ruthenium tetroxide obtained in situ by reacting RuO 2 hydrate or RuCl 3 with the alkaline periodate.
