2-Aza-4′-demethylepipodophyllotoxin (6) has been efficiently synthesized in 40% yield from (7) in three steps by a highly regioselctive and stereoselctive cyclization of (8) with (9).

Optically active and racemic podophyllotoxin aza-analogues 3 approximately 7 were designed and synthesized by a highly stereoselective condensation reaction of a cyclic urethane 10 or 16 with 3,4,5-trimethoxybenzaldehyde 11 and were found to show a promising in vitro and in vivo antitumor activity.
