Steroid path 1

The basic molecular structure of a steroid includes four rings—three six-membered and one five-membered—which are built entirely of carbon atoms. The biological function of a steroid depends on the groups attached to these rings. Diosgenin, for instance, has two additional rings (highlighted here in red). To modify diosgenin's molecular structure to the desired cortisone, our virtual chemist needs to perform a series of chemical reactions.
