An efficient method for synthesis of 6-alkynyl-substituted androstane derivatives was developed via the Pd-catalyzed Sonogashira—Hagihara coupling reaction. The use of AgCl as the cocatalyst (instead of traditionally used CuI) was shown to increase the activity of the catalytic system in several cases.

Chlorine at an sp 2 -carbon in steroids has been shown to be reactive in Suzuki-Miyaura cross-coupling reactions with either Ni or Pd catalysts. The coupling of analogous 6-bromo derivatives has also been demonstrated to be applicable to a wider scope of substrates. The Suzuki-Miyaura arylation of 6-bromo-Δ 3 , 5 -steroid enol ethers with subsequent hydrolysis is a useful route to 6-arylated steroids

A general procedure has been developed for the introduction of hydrophobic alkyl groups into positions 6, 3, and 17 of steroid molecules via palladium-catalyzed Negishi reaction of halogen-substituted steroids with benzyl- and alkylzinc halides.
