The synthesis of (+/-)-3-[1-carboxy-3-alpha-4-alpha-dihydroxycyclohex-1-en-5-beta-yl]-2-methylenepropionic acid, a carba analogue of 5-enolpyruvylshikimic acid from methyl (+/-)-homogabaculinate is described. In addition, both enantiomers of methyl homogabaculinate have been obtained from the Diels Alder reaction of 1-tert-butoxy-carbonyl-1,2-dihydropyridine and the N-acryloyl derivative of Oppolzer's bomane 10,2-sultam.

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
