Abstract

Procedure for obtaining 19-nor-steroids, characterized, because the 4,6-3-oxo-19-hydroxy-steroidians are oxidized to 19-acid-steroids, these are decarboxylated by heating and, if desired, Δ 5 (10), 6-3-oxo-19-nor-steroidedienes, if any formed, are isomerized to Δ 4,6-3-oxo-19-nor-esteroidedienes and/or Δ 4 , 6-3-oxo-19-nor-steroids obtained are halogenated in position 4.
