Abstract
Process for the preparation of podophylic acid derivatives, especially novel amides of the general formula I R-NH2 I where R means the C22H23O8 residue of the podophilic and picropodophilic stereoisomeric acid, characterized in that the stereoisomeric hydrazides of the general formula II R-NH-NH2 II where R has the meaning indicated above, they are treated with metals used as hydrolyzing catalysts, preferably with Raney nickel.
