Versuchsvorschrift

Platinum(IV)oxide (Adam's catalyst) (0.05 g) was added to a solution of 4′,7-diacetoxyisoflavanone (0.25 g, 0.7 mmol) in ethyl acetate (40 ml) and the mixture was stirred at room temperature under a hydrogen atmosphere for 55 h. The catalyst was removed by filtration through Celite and the filtrate was evaporated in vacuo to yield predominantly the cis-4′,7-diacetoxyisoflavan-4-ol.
