Abstract

Preparation process of 3-oxo 17beta-hydroxy δ 5 (10) -strene, characterized in that a 3-oxo is converted 17beta-hydroxy or 17beta-acyloxy δ 4,9-estradiene, into a cyclic ketal of the 3-oxo 17beta -hydroxy δ 5 (10), 9 (11) -estradiene, the double bond 9,11 of the latter compound is selectively reduced, and then the ketone is released in 3.
