The present invention provides an improved synthesis of a class of steroid saponins. Furthermore, the present invention provides a method of selectively discriminating between the C2 and C3 hydroxyl groups of a mono-glycosylated steroid saponin—a key step in the preparation of this class of compounds. Additionally, the present invention provides a range of steroid saponin derivatives, and methods of making them.
