Chemical name: (S)-Allylglycine (>98%, >99%ee) // Synonyms: (S)-2-Aminopent-4-enoic acid, 4,5-Dehydro-L-norleucine (>98%, >99%ee)
|Molecular weight:||115,13 g/mol|
Allylglycine is a glycine derivative. It is an inhibitor of the enzyme glutamate decarboxylase.
Inhibition of glutamate decarboxylase blocks GABA biosynthesis, leading to lower levels of the neurotransmitter. It is used to induce convulsions in animals in scientific studies.
N-Allyloxycarbonyl (Alloc) are widely used protecting groups, i.e. for amines and amino acids, as they are quantitatively andvery rapidly converted to free amino compounds by palladium. Deprotection of allyl (All) carboxylates and allyl aryl ethers can also be carried out accordingly.
All and Alloc are fully compatible with Fmoc/tBu and Boc/Bzl strategies, as well as with Z protecting groups.
