The synthesis of the alkamides 2Z,4E-undeca-2,4-dien-8,10-diynoic acid isobutyl amide (1) and 2Z,4E-undeca-2,4-dien-8,10-diynoic acid isobutyl amide (5) was accomplished by organometallic coupling followed by introduction of the doubly unsaturated amide moiety. The distribution of these two amides in accessions of the nine species of Echinacea was determined.
合成了2Z,4E-十一烯-2,4-二烯-8,10-二炔酸异丁酰胺(1)和2Z,4E-十一烯-2,4-二烯-8,10-二炔酸异丁酰胺(5),通过有机金属偶联反应,随后引入双不饱和酰胺部分。还确定了这两种酰胺在九种紫锥花物种中的分布情况。
