These data and product analysis indicate that the former three esters are solvolysed with considerable double bond participation [resulting in the case of the (E)-3-esters in intramolecular cyclopropane ring closure], and that this interaction is unimportant for the (Z)-3β-tosylate. On the basis of conformational analysis of the starting tosylates and stereoelectronic requirements for homoallylic interaction, a possible mechanistic pathway for these solvolyses is proposed.

AB  - The solvolysis of (Z)- and (E)-3β-acyloxy-5,10-seco-1(10)-cholesten-5β-ol p-nitrobenzoates 4 and 5 has been investigated and compared with the solvolytic reactivity of the epimeric (Z)- and (E)-5α-p-nitrobenzoates 1 and 2, as well as of the reference compound, i.e. the 1,10-saturated 5α-p-nitrobenzoate. Kinetic data and product analysis revealed that the relative spatial orientation of the 1(10)-olefinic double bond and the chiral center at C(5) in the 10-membered ring, which these secosteroidal 5-p-nitrobenzoates can adopt in the transition state, is the main factor which determines their solvolytic behaviour, so that the esters 1,2 and 5 solvolyse with transannular double bond participation, while such an interaction is not present in the case of the (Z)-5β-ester 4. © 1979.

AB  - When 7α-acetoxy-3,3 : 17,17-bis(ethylenedioxy)-5,10-epoxy-5β, 10β-oestran-6-one (2), formed by lead tetra-acetate acetoxylation of the parent compound (1), is heated with alkali, it undergoes ring B aromatization to give 3,3: 17,17-bis(ethylenedioxy)-5(10),6,8-oestratriene-6,7-diol (3), without configurational change at C(14); deacetalization of the corresponding diacetate (4), followed by lead tetra-acetate aromatization of ring A in the resulting diketone (5), produces 6,7-diacetoxy-equilenin (6), which is finally converted into its 3-acetate (7).
