A reaction between two prebiotically plausible building blocks, hydantoin and glyoxylate, generates both the nucleobase orotate, a precursor of biological pyrimidines, and pyruvate, a core metabolite in the citric acid cycle and amino acid biosynthesis. The reaction proceeds in water to provide significant yields of the two widely divergent chemical motifs. Additionally, the reaction of thiohydantoin...
Ausgehend von Formamid werden Mechanismen für die Umwandlung in Purin und Adenin vorgeschlagen (siehe Schema: Purin (R=H, X=H), Adenin (R=CN, X=NH2, R′=CONH2). Parallelen zu diesen plausiblen präbiotischen Routen könnten zu den Ursprüngen der metabolischen Purinring‐Biosynthese führen.
