Abstract

The crystal and molecular structures of 17‐ethylenedioxy‐3‐methoxy‐6,7,8‐methylidyne‐1,3,5(10)‐estratriene (1) and of 17β‐bromo‐acetoxy‐3‐methoxy‐8α‐methyl‐1,3,5(10),6‐estratetraene (3) have been determined by X‐ray analysis. A short discussion of the structures is given, and a new picture of the structure‐activity relation of estrogenics is proposed.
