Abstract

Because of their potential prebiotic origin and relative chemical stability, urea, biuret, formic acid, and glycine amide might have played a role in the assembly process of purine bases. In this paper, we describe a short reaction path to purine nucleobases from these acyclic precursors. The formation of different purines was verified by UV and NMR spectroscopy, as well as by mass spectrometry.
