Abstract The mechanism of the condensation of dilute aqueous solutions of HCN and the products formed by these reactions have been investigated. The initial HCN condensation reactions yield3, a compound which is readily oxidized to4. A similar oxidation of5 to6 was also observed. Urea is formed on hydrolysis of4. The oxidation-reduction products formed from HCN may be in part a consequence of the oxidation of3. It has been established by combination GC/MS that the amino acids glycine, diaminosuccinic acid, α-amino-isobutyric acid, aspartic acid, alanine and isoleucine are released on acid hydrolysis of the ‘HCN polymer’. Hydantoin (7), 5,5-dimethylhydantoin (8) and 5-carboxymethyldenehydantoin (10) are also released on acid hydrolysis of the HCN condensation products. The direct conversion of the dicarbonyl derivative, of diaminosuccinic acid to orotic acid via10 at pH 8 has been observed. This conversion suggests a direct route to pyrimidines from HCN.
