A series of novel α-aminophosphonates were synthesized from diterpenic dehydroabietylamine, and their structures were characterized by IR, 1H NMR, and 31P NMR spectroscopy. Their antitumor activities against SMMC7721 liver cancer cells were evaluated by the MTT method. Compounds 4 and 6 exhibited higher activities even at very low concentrations, and the inhibition ratios reached 75% and 79% at 0.1
