摘要：
Lambertianic acid was selectively transformed at the carboxylic group. Synthetic methods for natural labdanoids, i.e., lambertianic acid methyl ester and lambertianol, were proposed. New N-containing diterpenoid derivatives with alkyl(aryl)amide, dialkylamide, hydrazide, N-hydroxycarbamoyl, and nitrile groups in the C-4 position of the labdane skeleton were synthesized via reactions of lambertianic acid chloride with aliphatic and aromatic amines, amino acids, hydrazine, and hydroxylamine. Compounds with higher cytotoxicity than lambertianic acid against MCF-7, HeLa, and HepG2 (MTT assay) human tumor cell lines were obtained. The IC50 value of the most active lambertianic acid N-hydroxycarbamoyl derivative was 15 mu M (selectivity index >7).
