(Z)-2-(β-D-glucopyranosyloxy)-3-phenylpropenoic acid 1, an enolic glucoside of phenylpyruvic acid, representing the first unequivocal evidence for the latter's presence in woody plants. The synthesis of a derivative 2 of the natural product, and of related regiomeric and geometrical isomers 3,4 and 5, and the biosynthetic significance in relation to the shikimic acid pathway are discussed.
Fabaceae的成员Aspalathus linearis的叶子和茎包含(Z)-2-(β- D-葡萄糖吡喃糖基氧基)-3-苯基丙酸1,是苯基丙酮酸的烯醇式葡萄糖苷,代表了后者的第一个明确证据。存在于木本植物中。讨论了天然产物的衍生物2的合成,相关的区域异构体和几何异构体3,4和5的合成以及与sh草酸途径有关的生物合成意义。
