Attempts to synthesize kainic acid [PDF]

open access: yes, 1982
Attempts were made to synthesise a conformationally restricted analogue of kainic acid wherein the double bond was confined in a ring-system. The stratagem involved an intramolecular Diels-Alder reaction but could not be tested as the precursors to ...
