                                    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.
