Dehydroaspartic acid derivatives.
Dipeptides of threo- and erythro-beta-hydroxyaspartic acid were transformed into O-tosyl derivatives, which on base-catalyzed elimination gave aminofumaric acid derivatives. The possible mechanism of this process and the spectroscopic properties of the elimination products are discussed.
