preparation or as antagonist of the actions of the selective agonists NMDA, quisqualic acid, and kainic acid. The chain-elongated glutamate derivatives with potential antagonist activity proved to be weak and frequently nonselective antagonists in this assay. The most noteworthy result was that trans isomer 7b was a very potent agonist, approximately 20 times more active than NMDA at NMDAreceptors, while the

Addition of hydrazoicacid or benzylamine to 1-(arylsulfonyl) bicyclobutanes introduces the nitrogen nucleophlle at position 3 of the derived cyclobutane, even when a carboxyl derivative is present at this position as a second activating group. Precursors of α-amino cyclobutane carboxylic acids may thus be obtained and these can be further transformed to the title diacids via carbonylation α to the
