Verfahren zur Herstellung von carboxylgruppenhaltigen Abbauprodukten von Verbindungen der Oestranreihe Es wurde bereits ein Verfahren vorgeschla- gen, nach welchem es gelingt, 3,17 Dialkoliole der Oestranreihe durch Einwirkung von Oxy- dationsmitteln. die in der Lage sind, den am Phenanthrenkern haftenden Cyclohentanring aufzusprengen. in carbo--,cy lgruppenhaltige Ab- bauprodukte überzuführen.
