Abstract

Process for the preparation of 9alpha-lOalpha-epoxy 2alpha-lower alkyl 19-nor testosterone, of its esters and ethers, characterized in that it is cyclized by means of a basic function agent, a 17beta-hydroxy or 17beta-acyloxy; , 5-dry 3,5-dioxo-2-lower alkyl Δ 9-premiere in a 3-oxo 17beta-hydroxy or 17beta-acyloxy 2-lower alkyl Δ 4,9-estradiene corresponding, separates 2alpha and 2beta epimers , the 2alpha epimer is subjected to the action of a peracid, a 9alpha, 10alpha-epoxy-2alpha-lower alkyl-19-nor-testosterone is obtained, free or esterified, and is transformed, if necessary, into the desired functional derivative.
