Abstract

A process for the preparation of new A-nor B-homo steroids, characterized in that 19-nor-3-methoxy 20-hydroxy δ2.5 (10) -pregnadiene is oxidized by the action of aluminum isopropylate, is isolated -nor 3-methoxy 20-oxo δ2,5 (10) -pregnadiene, the latter is treated with an acidic agent to obtain 19-nor 3,20-dioxo δ5 (10) -pregneno, is actuated ozone on this compound, 3,5,10,20 -tetroxo 5,10-dry 19-nor pregnane is isolated, which is cyclized by acid treatment, obtaining the 3,6,20-trioxo A-nor B-homo δ 5 (10) 19-nor pregnene, the latter is selectively reduced by the action of an alkaline mixed hydride, and 3,6,20-trioxo A-nor B-homo 10 ξ9-nor pregnane.
