DL-2-Amino-4-pentenoic acid Chemical Properties, Uses, Production

Chemical Properties

white crystalline powder

Uses

peptide synthesis

Biochem/physiol Actions

DL-2-Allylglycine is a racemic mixture of L- and D-allylglycine. D-allylglycine is the enantiomer of L-allylglycine, a glutamate decarboxylase (GAD) inhibitor used in GABA research. D-allylglycine may be used as a control supplement versus L-allylglycine in GABA research. D-allylglycine is used in the organic synthesis of cyclic opioid peptide agonists and antagonists.

Purification Methods

Dissolve it in absolute EtOH and precipitate it with pyridine, then recrystallise it from aqueous EtOH [RF on paper in BuOH/EtOH/NH3/H2O (4:4:1:1:) is 0.37]. The hydrobromide has m 136-140o (from EtOAc) and the phenylureido derivative has m 159-161o. [Schgl Monatsh Chem 89 377 1958, Beilstein 4 IV 2852.]
