Document Type and Number:
WIPO Patent Application WO2002101014
Kind Code:
A3
Abstract:
A novel process for making estra-4,9(10)-diene-3,17-dione steroids from readily available 19-nor-androst-4-ene-3-one steroids by a straightforward three-step process. Products of this process are important intermediates in the preparation of biologically active substances.
