Abstract
Novel syn- and anti-oximes of degraded pseudosapogenins, having the partial structural formula <FORM:1045760/C2/1> where only the D-ring is shown and Ac represents an acyl group, are obtained in a process in which an ester of a pseudosapogenin is reacted with a nitrite to give a 16-(11-acyloxypentanoyl) derivative of 20-oximido-pregnane. Treatment of the resultant oxime with acid gives the corresponding 20 - oximido - 16,17 - dehydro steroid.
