Uncatalyzed Guanosine Phosphorylation under Potentially Prebiotic Conditions

Chemistry – A European Journal, EarlyView.
Pyrophosphate acts as phosphorylating agent of guanosine under simple wet‐dry cycles without condensing agent and inorganic catalysts to afford cyclic guanosine monophosphate derivatives useful for oligomerization in prebiotic processes. ABSTRACT The phosphorylation of nucleosides and their subsequent polymerization are key issues in the study of the ...
