Kuroda, Chiaki published the artcileReaction of Aminomalononitrile and Benzylic Compounds as a Plausible Route to Phenylalanine, COA of Formula: C10H11N3O3S, the publication is Natural Product Communications (2020), 15(1), 1934578X20901417, database is CAplus.
As a possible route to phenylalanine, reaction of aminomalononitrile with benzylic compounds was studied. 2-Benzyl-2-aminomalononitrile was obtained in a good yield when aminomalononitrile p-toluenesulfonate was treated with benzyl bromide in THF using triethylamine as a base. The reaction proceeded in the presence of water. 2-Benzyl-2-aminomalononitrile was hydrolyzed to afford phenylalanine. The aminomalononitrile route can explain the presence of not only 1 methylene in aromatic amino acids, but also α-hydrogen in all 20 proteinogenic amino acids.
