Abstract
In the course of the partial synthesis of 18-norestradiol, an X-ray analysi s of an appropriately crystallizing intermediate, C20H25NO3S3, was carried out in order to determine its absolute configuration. The unusual D-seco st eroid displays configurations at C8, C9 and C14 not altered in comparison w ith the starting material, estrone.
