✦ Synopsis

New Synthesis of Estradiol from Androsta-1,4-diene-3,17-dione.

-A new method for the aromatization of ring A in androsta-1,4-diene-3,17-dione (I) via reduction to the corresponding dienediol (II) followed by double C,Odeprotonation of ring A is reported. This two-step transformation of (I) into estradiol (III) surpasses competing transformations of (I) into (III) with respect to simplicity and efficiency and can also be used for aromatization of ring A in related steroids bearing a 19-methyl group.
