title: [Synthesis of gestodene].
abstract: The synthesis of the new progestogen, 17 alpha-ethinyl-17 beta-hydroxy-18-methyl-4,15-estradien-3-one (gestodene, 6), starting from 18-methyl-4-estren-3,17-dione (1) can be accomplished by several methods. The oral progestational activity of gestodene is greater than that of levonorgestrel. Gestodene, in combination with ethinylestradiol, is contained in a recently developed oral contraceptive.
