    摘要: This invention relates to a process for the preparation of 10-(2-propynyl)-estr-4-ene-3,17-dione, whereby this compound is synthesized utilizing ketals prepared from the addition of 2,2-dimethyl-1,3-propanediol to the starting compound, 19-norandrost-5(10)-ene-3,17-dione (NAD). A new process for the addition of the propynyl group to steroid epoxides by means of higher order cuprates is also described herein.
