| Popis: | The synthesis of title compound (1) by a series of functional group transformations in a high overall yield from the commercially available diosgenin is described. The synthesis requires 5-alpha, 6-beta-bromohydrin formation, radical-initiated ring formation, regioselective opening of the epoxy ring, and regioselective cyclopropanation as crucial steps. |
