Starting from 3 -hydroxy-lup-20(29)-en-23,28-dioic acid, which is isolated with high yield from the plant Schefflera octophylla (Lour.) Harms (Araliaceae), a series of amide esters and amide acids with amino acids have been synthesized. All the synthesized compounds are new. Their structures were determined by IR, MS and NMR spectroscopic methods.
