ABSTRACT Novel antitumor epipodophyllotoxin glucoside lactam derivatives are prepared by first converting the lactone ring of the parent compound to the open-chain trans-hydroxy hydrazide, condensing the hydrazide with a carbonyl compound to form the corresponding hydrazone, and finally cyclizing the trans-hydroxy hydrazone using diethylazodicarboxylate and triphenylphosphine.
