The regioselective opening of the F ring of 22-oxo-23-spiroketals using a saturated solution of HCl in acetic anhydride yielded novel cholestanic frameworks with pyranone or cyclopentenone E rings. The structures of the new derivatives of sarsasapogenin, dios...

We report the deacylation of (20R)-20-acetyl-23,24-dinorcholanic lactones by hydrazine hydrate, under microwave irradiation in high yields. The elimination of the 20-acetyl group proceeded with retention of configuration which contrast with other proved deacy...
