Abstract

"Procedure for obtaining carbocyclic compounds", especially compounds of formula I, where R1 is hydrogen, hydroxyl or an acyloxy group and R2 and R3 hydrogen, characterized in that the 3', 4', 5'-demethoxy-isopodophyllinic acid by dissociation of a water molecule is transformed into 3', 4', 5'-demethoxy-isopodophyllotoxin (formula VI) and this, if appropriate, is acylated or catalytically hydrogenated to the 4-deoxy compound.
