Process for alkynylating 16-substituted-17-keto steroids |
abstract |
A process ethynylates 16-methylene-17-keto steroids to the corresponding 16-methylene-17α-ethynyl-17β-hydroxy steroids by treatment with silyl-protected lithium acetylides followed by further desilylation. The resulting products are useful intermediates in the preparation of several pharmaceutically active agents, such as e.g. Nestorone® or melengestrol acetate. |
