Ferris, James P. published the artcileStudies in prebiotic synthesis. I. Aminomalononitrile and 4-amino-5-cyanoimidazole, Name: 2-Aminomalononitrile 4-methylbenzenesulfonate, the publication is Journal of the American Chemical Society (1966), 88(16), 3829-31, database is CAplus and MEDLINE.
The syntheses of aminomalononitrile and 4-amino-5-cyanoimidazole are described. Acid anhydrides react with aminomalononitrile to yield oxazoles. Aminomalononitrile is converted to diaminomaleonitrile by cyanide and to 4-amino-5-cyanoimidazole by formamidine. Adenine results from the reaction of 4-amino-5-cyanoimidazole with formamidine. 4-Cyano-5-aminooxazole is converted to 7-aminooxazolo[5,4-d]pyrimidine on treatment with formamidine. 16 references.
