摘要
Abstract
In order to obtain more effective glycyrrhetinic derivatives, 3-amino acid derivatives were synthesized from glycyrrhetinic acid via deoxidation of the 11-carbonyl group, ethyl esterification of the 30-carboxylic group and esterification of 3-hydroxyl group using Fmoc-protected amino acids, which include methionine, threonine, valine and phenylalanine, by dicyclohexylcarbodiimide(DCC)/dirnethylaminopyridine (DMAP) coupling method in tetrahydrofuran. The final products were obtained by removing Fmoc using F(CH2C12):F((C2H5)2NH) =1:1 solvent mixture with 80% -87% yields and characterized by 'H NMR and MS. Preliminary pharmacological research showed that compounds 5a - 5d could protect the growth of E col. , Bacillus Subtilis and Yeast against high level of N,N-dimethylformamide.关键词
