The synthesis of ent-19-nortestosterone from natural 19-nortestosterone is described. The synthetic sequence takes advantage of the ‘near symmetry’ properties of the steroid; removal/introduction of a methyl group and conversion of the A- into the D-ring and vice versa eventually results in overall inversion of the stereochemistry.
