Abstract
Process for obtaining hydrazonic derivatives of the general formula I ** (See formula) ** where R represents the C22H23O8 moiety of the podophylic acid and picropodophilic stereoisomeric acid, R1 is by hydrogen or by a lower alkyl and R2 by a heterocyclic moiety or by an alkyl, aralkyl, alkylaryl or aryl group, which may be substituted by halogen or hydroxyl, alkoxy or a primary, secondary or tertiary sulfonic or amine group, or R1 and R2 together with the C atom, which binds them, mean a bivalent alicyclic or heterocyclic moiety, characterized in that the stereoisomeric hydrazides of the general formula II R-NH-NH2 II where R has the meaning indicated above, they are reacted with carbonyl compounds of the general formula III ** (See formula) ** where R1 and R2 have the same meaning as indicated above.
