Avenic acid A (1), an amino acid derivative possessing an iron chelating activity and excretedfrom the root of Avena sativa L. was synthesized in optically active form by successive reductive coupling of protected L-aspartic β-semialdehyde and L-malic semialdehyde with L-homoserine lactone. 2′-Deoxymugineicacid (2), a related substance was also synthesized by the same method by which the stereostructure
Avenic acid A (1) 是一种氨基酸衍生物,具有铁螯合活性,从 Avena sativa L. 的根中分泌出来,通过受保护的 L-天冬氨酸 β-半醛和 L-苹果酸半醛与 L-天冬氨酸 β-半醛和 L-苹果半醛的连续还原偶联,以旋光形式合成。 L-高丝氨酸内酯。2'-脱氧麦根酸(2),也用同样的方法合成了相关物质,证明该氨基酸衍生物的立体结构为2(S),3'(S),3"(S)-N -[3-(3-羟基-3-羧丙基氨基)-3-羧丙基]-氮杂环丁烷-2-羧酸。
