The synthesis of (±)-3-(1-carboxy-3α,4α-dihydroxycyclohex-1-en-5β-yl)-2-methylidenepropionic acid, a methylene analogue of 5-enolpyruvylshikimic acid, from methyl 3α,4α-isopropylidene-5β-iodomethylcyclohex-1-ene-1-carboxylate is described. The starting compound is obtained from (±)-methyl homogabaculate. In addition, both enantiomers of methyl homogabacuate have been synthesised from a Diels-Alder
由3-α,4α-异亚丙基甲基合成(±)-3-(1-羧基-3α,4α-二羟基环己基-1-en-5β-基)-2-亚甲基丙酸,5-烯丙基丙酮基shi草酸的亚甲基类似物描述了-5β-碘甲基环己-1-烯-1-羧酸酯。起始化合物获自(±)-甲基高古草酸酯。此外,高巴果酸甲酯的两种对映异构体均由1- t丁氧基羰基1,2-二氢吡啶的Diels-Alder环加成反应和Oppolzer的10,2-苏丹草的N-丙烯酰基衍生物合成。
