    A novel enantioselective total synthesis of the oral contraceptive desogestrel (2) is described, in which the tetracyclic steroid core is formed by a sequence of two consecutive Heck reactions. Conversion of the known enantiopure diketone 7 led to the chiral bicycle 6 which was used for a diastereoselective intermolecular Heck reaction with vinyliodide 5 to give 15. In the following intramolecular
