Divergent prebiotic synthesis of ribonucleotides — •Matthew Powner — UCL, London, UK

RNA is a leading candidate for the original informational biopolymer of life, however a common prebiotic pathways to both purine and pyrimidine ribonucleotides remain elusive. We recently described a prebiotically plausible synthesis of pyrimidine ribonucleotides, but both purine and pyrimidine nucleotides must be synthesised together to access an information rich biopolymer. A divergent strategy to synthesise pyrimidine and 8-oxo-purine ribonucleotides from prebiotic precursors will demonstrate for the first time generational parity between 8-oxo-purine and pyrimidine heterocycles, allowing stepwise synthesis with regiospecific, stereoselective glycosidation and simultaneous phosphorylation with stereochemical inversion to furnish the β-ribo-stereochemistry found in the biological nucleic acids.
