17α-Butadiynyl-17β-hydroxy-steroids have been prepared by reaction of 17-oxo-steroids with monosodio-butadiyne and converted, by reaction with hydrogen sulphide, into 17α-(2′-thienyl) 17β-hydroxy-steroids.

Abstract The synthesis of some 17α-butadiynyl-17β-hydroxyestrene derivatives by reaction of 17 -ketones with lithium or sodium diacetylide is described. Surprisingly 17α-butadiynyl-3, 17β-dihydroxy-1,3,5 (10) -estratriene (V) and its 3-methylether (VI) exhibit greatly enhanced contraceptive activity and reduced estrogenicity relative to their ethynyl analogues, whereas the other compounds herein reported
