The Reaction of Some 1α,2α- and 2α,3α-Methylene Steroids with Hydrobromic Acid

Hanson, James R.,Knights, Steve G.

, p. 24 - 28 (2007/10/02)

Treatment of 17β-acetoxy-methyleneandrost-4-en-3-one under the conditions of the dienone-phenol rearrangement affords 17β-acetoxy-1α-bromomethylandrost-4-en-3-one rather than a phenol.The corresponding 3α-alcohol gave a 1α-bromothexyl-3,5-diene rather than an aromatic compounds. 2α,3α-methyleneandrost-5-ene-4,17-dione also gave a 2α-bromomethylandrost-5-ene-4,17-dione rather than a phenol.
