Summary
The reactions of glycine with inorganic polyphosphates in the solid state have been studied. The formation of peptides up to the decamer occurs at moderate temperatures (r.t.−100°C) in the presence of imidazole and magnesium chloride. If adenosine 5′-monophosphate is added to the reaction mixture, 2′(3′)-O-glycyl adenosine 5′-monophosphate is also obtained. These reactions could have occurred on the primitive earth.
