✦ Synopsis

Syntheses are described from a common labeled intermediate of P-cyanoalanine, asparagine, and aspartic acid, each of the L conjiguration and labeled with carbon-14 in carbon-four. Radiochemical purities were 96, 99.7, and 99 %. The common source of carbon-14 was ethyl aCetyl-DL-P-~yanoalaninate-4-~~C, which was prepared from commercially available potassium cyanide-14C by an extension of the studies of Atkinson and Hellmann and Folz.
