for these compounds and for a sample of a 1,2-dideuterated androst-4-ene-3-one; the latter is formed nonstereospecifically by reduction of the C-1(2) double bond of a Δ1,4-diene-3-one. Aromatization by placental microsomes occurs with retention of deuterium at C-4 and C-6, but with some loss from C-16. The aromatization of 19-d1 and 19,19,19-d3 steroids in the presence of 16,16-d2 steroids has been

Abstract The solvolysis of 3β,19-dihydroxyandrost-5-ene-17-one-3-acetate 19-tosylate (Ib) led to the Δ6-5, 19-cyclo steroid IIa or a variety of 6α-substituted 5,19-cyclopropanes V depending upon the reaction conditions. The possibility that these reactions proceed through an intermediate homoallylic bridged cation is discussed. The formation of 6β,19-cyclobutanes from 19-hydroxyandrost-4-ene 3,17-dione

Solvolysis of 3,17-Dioxo-19-mesyloxy-Δ4-androstene (2) in methanolic sodium methylate solution yields a mixture of the 6β, 19-cyclo-androstane derivatives 3 and 4. 3,17-Diethylenedioxy-19-mesyloxy-Δ5-androstene (11) in boiling pyridine is converted into 3,17-diethylenedioxy-5β, 19-cyclo-Δ6-androstene (12).
