title: Formation of nucleoside 5'-phosphoramidates under potentially prebiological conditions.
abstract: Adenosine 5'-phosphoramidates form when solutions containing adenosine 5'-polyphosphates pnA (n greater than or equal to 3) or P1, P2-diadenosine 5'-diphosphate and amines are allowed to dry out. Mg ions catalyze these reactions. We have studied systems containing ammonia, imidazole, glycine, ethylenediamine and histamine. The yields of adenosine 5'-phosphoramidates range from 10-50% based on the nucleotide. The prebiotic significance of the reactions is discussed.
