✦ Synopsis
Rearrangement of 3‐Thioxo‐Δ^1,4^‐steroids, a New Approach of Steroid Thiols
3‐Thioxoandrosta‐1,4‐dien‐17‐one (1) is subjected to a dienthion‐thiophenol rearrangement in aprotic and protic solvents in the presence of an acid catalyst resulting in the formation of 1‐(acetylthio)‐4‐methylestra‐1,3,5(10)‐trien‐17‐one (2). 1‐mercapto‐4‐methylestra‐1,3,5(10)‐trien‐17‐one (3), and the dimer 1,1′‐(dithio)bis[4‐methylestra‐1,3,5(10)‐trien‐17‐one] (4) as the reaction products. The mercapto compound 3 tends to be autoxidized to the sulfide 4.
