To find podophyllotoxin compounds with superior bioactivitiy and less toxicity, a series of novel conjugates of ring‐A‐modified 4‐epipodophyllotoxin and stavudine with amino acids as spacers were synthesized, i.e., the N‐[(2′,3′‐didehydro‐3′‐deoxythymidin‐5′‐O‐yl)carbonyl]‐substituted L‐amino acid rel‐(3aR,4S,9R,9aR)‐1,3,3a,4,9,9a‐hexahydro‐6,7‐dimethoxy‐1‐oxo‐9‐(3,4,5‐trimethoxyphenyl)naphtho[2,3‐c]furan‐4‐yl
