six different 3-methyl-5-aryl-2,4-pentadienoic acids and esters were synthesized using the Reformatsky and Wittig reactions. The different geometrical isomers were conveniently separated by the dry column technique. Assignment of configuration of the pentadienoic side chain was based on NMR and UV properties. The biological activities of the aromatic analogs of ABA were determined in four bioassays
摘要 使用 Reformatsky 和 Wittig 反应合成了 36 种不同的 3-甲基-5-芳基-2,4-戊二烯酸和酯。不同的几何异构体可以通过干柱技术方便地分离。戊二烯侧链的构型分配基于NMR和UV特性。ABA 芳香族类似物的生物活性在四种生物测定中确定。大多数类似物的活性低于天然激素。在所有四种生物测定中,只有 3-methyl-5-p-chlorophenyl Δ 2 - trans , Δ 4 - trans -pentadienoic acid 表现出高 ABA 样活性。
