Claims
- 1. A compound of general formula ##STR4## in which St represents rings A. B, C and D of naturally occuring 3.beta.-oxygenated aglycones with their respective substituents attached thereto selected from the group consisting of digitoxigenin, periplogenin, digoxigenin and gitoxigenin, R represents a substituent on the 3.beta.-oxygen of the aglycone selected from the group consisting of hydrogen, a lower aliphatic acyl group containing 2 to 4 carbon atoms and in which the 2-methoxy-3-cyanofuryl group is attached to the steroid moiety St at position 17.beta..
- 2. 21,23-Epoxy-3.beta.,14-dihydroxy-23-methoxy-24-nor-5.beta.,14.beta.-chola-20,22-diene-22-carbonitrile 3-acetate as claimed in claim 1.
- 3. A compound of formula ##STR5## in which St-OR represents rings A, B, C and D of naturally occuring 3.beta.-oxygenated aglycones with their respective substituents attached thereto selected from the group consisting of digitoxigenin, periplogenin, digoxigenin and gitoxigenin, R represents a substituent on the 3.beta.-oxygen of the aglycone selected from the group consisting of hydrogen, a lower aliphatic acyl group containing from 2 to 4 carbon atoms and in which the cyano lactone ring is attached to the steroid moiety of St at position 17.beta..
- 4. 22-Cyano-3.beta.,14-dihydroxy-5.beta.-card-20(22)-enolide 3-acetate, as claimed in claim 3.
