Electrophilic fluorination of enantiomerically pure 2-pyrrolidinones (4) derived from (L)-glutamic acid has been investigated as a method for the synthesis of single stereoisomers of 4-fluorinated glutamic acids. Reaction of the lactam enolate derived from 9 with NFSi results in a

Methotrexate is glutamylated in cultured hepatoma cells to derivatives that contain a total of 2 to 5 gamma-glutamyl residues. The rate of polyglutamate formation and extent of accumulation are saturable with respect to both medium concentration of methotrexate and time.

Two pentapeptides Phe-Leu-X-Glu-Val where X is either the L-threo-gamma-fluoroglutamic acid or the L-erythro-isomer have been synthesized and tested as substrates in the vitamin K-dependent carboxylation. Both peptides are carboxylated, but the reaction occurs exclusively on the glutamic acid of the

Corynebacterium glutamicum is a biotin auxotroph that secretes L-glutamic acid in response to biotin limitation; this process is employed in industrial L-glutamic acid production. Fatty acid ester surfactants and penicillin also induce L-glutamic acid secretion, even in the presence of
