Abstract

Chlorine at an sp2-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-Δ3,5-steroid enol ethers with subsequent hydrolysis is a useful route to 6-arylated steroids bearing aryl at a saturated carbon.
