N-Phenylglycine is an organic compound with the formula C 6 H 5 NHCH 2 CO 2 H. This white solid achieved fame as the industrial precursor to indigo dye . [ 1 ] It is a non-proteinogenic alpha amino acid related to sarcosine , but with an N - phenyl group in place of N - methyl .
Phenylglycine is the organic compound with the formula C 6 H 5 CH(NH 2)CO 2 H. It is a non-proteinogenic alpha amino acid related to alanine, but with a phenyl group in place of the methyl group. It is a white solid. The compound exhibits some biological activity. [1]
The first commercially practical route of producing indigo is credited to Pfleger in 1901. In this process, N-phenylglycine is treated with a molten mixture of sodium hydroxide, potassium hydroxide, and sodamide. This highly sensitive melt produces indoxyl, which is subsequently oxidized in air to form indigo. Variations of this method are ...
N-Phenylacetyl-l-prolylglycine ethyl ester is promoted as a nootropic and is a prodrug of cyclic glycine-proline. [a] [2] Other names include the brand name Noopept (Russian: Ноопепт), developmental code GVS-111, and proposed INN omberacetam. [2] [3] [4] Its synthesis was first reported in 1996. [2] It is orally available.

4-Hydroxyphenylglycine (HPG) is a non-proteogenic amino acid found in vancomycin and related glycopeptides. HPG is synthesized from the shikimic acid pathway and requires four enzymes to synthesize: [1] Both L- and D-HPG are used in the vancomycin class of antibiotics.
In the industrial production of indigo, sodium amide is a component of the highly basic mixture that induces cyclisation of N-phenylglycine. The reaction produces ammonia, which is recycled typically. [8] Pfleger's synthesis of indigo dye.
Polymerization is induced very slowly by camphorquinone, so amines such as N,N-dimethyl-p-toluidine, 2-ethyl-dimethylbenzoate, N-phenylglycine are generally added to increase the rate of curing. [1] It absorbs very weakly at 468 nm (extinction coefficient of 40 M −1 ·cm −1) giving it a pale yellow color. [1]
