Solasodine (I) has been subjected to a number of transformations. The following compounds have been obtained from it by described procedures: 3β-acetoxypregna-5,16-dien-20-one (II), 3β-acetoxypregn-5-en-20α-ol (III), and 3β-acetoxypregn-5-en-20β-ol (IV). The oxidation of (III) and (IV), the formation of an oxime, and the reduction of the oxime with sodium in ethanol, followed by Hess methylation, has
