Abstract

The invention comprises allopregnane- and n-pregnane-3,7,20-triones and their preparation by reacting an allopregnane- and n-pregnane-3,7-diol-20-one respectively with an oxidizing agent, e.g. chromic acid or chromium trioxide, potassium permanganate and N-bromacetamide in t-butanol. Examples are given.
