Synthesis of New Thio Corticosteroids including 1α,9α-Epidithio-11β,17α,21-trihydroxy-16β-methylpregn-4-ene-3,20-dione

Reaction of 3-keto 1α,5α-epidithio steroids with sulphuryl dichloride cleaves the tertiary carbon-sulphur bond to afford a Δ4-3-keto 1α-thiosulphenyl chloride which may be captured by various nucleophiles, in situ, to afford a number of novel 1α-substituted corticosteroid analogues.Intramolecular capture by a Δ9(11)-double bond leads to a synthesis of the title compound.
