Abstract
The structure of a new 14:15-seco-15-norpregnane derivative, 3'-14-epoxy-4' ,15-dioxaandrost-5-en-3 beta-yl acetate, C22H30O5, isolated from the ethyl acetate extract of Mandevilla illustris (Apocynaceae), is described. Its ch emical substructure contains an unusual 1-methyl-2,5,9-trioxatricyclo[4.2. 1.0(3,7)]nonane moiety. Features of the packing include an intermolecular C -H...O contact (C19-H...O5) of 3.230 (7) Angstrom.
