Cardiac glycosides, steroids of plant origin with a carbohydrate moiety at the 3p position, are a mainstay treatment for congestive heart failure. As such, there has been an ongoing interest in the synthesis of natural products related to digoxin and the preparation of analogs of the most bioactive compounds. This work has encompassed the preparation of parts of the parent steroids and unexpectedly modified hydroindene derivatives.

Kicha et al. 644) reported the occurrence of a new substance, aste-rosaponin Pj (960), in the Pacific starfish Patiria pectinifera. This saponin belongs to the group of 24-0-glycosidal steroids, but differed from those encounted previously, because the sugar moiety bears a sulfate residue. The structure of 960 was elucidated by spectroscopic and chemical methods. These latter included solvolysis of 960 to 961 and subsequent conversion by acetylation or methylation to the penta-acetate 962 or hexa-O-methyl derivative 963. Oxidation with CrOa-C5H5N resulted in the triketone 964, oxidation with CrOa-CHaCOOH in the diketone 965.
