Tổng hợp một số dẫn xuất ami của 3alpha-hydroxy-lup-20(29)-en-23,28 với axit amin

Abstract

Starting from 3α-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.
