Furyl intermediate* cardenolide made therefrom and synthesization of their isomers |
| abstract |
The invention relates to furyl intermediates and the preparation thereof, said intermediates being particularly useful in the preparation of synthetic cardenolides and their isomers. The process provides for the reaction of an unsaturated steroidal 17 ketone with a beta -furyl compound to produce an allylic alcohol which is subjected to acetylation and allylic rearrangement. The resulting material is then hydrogenated to produce the furyl intermediate. Cardenolides are formed therefrom by oxidation of the furyl intermediates. |
