mediated by evolving RNA. A novel potentiallyprebioticsynthesis of RNA is proposed involving polymerisation through aldol condensation followed by a retro-Amadori rearrangement and ring closure via a base-paired mesomeric heterocyclic betaine intermediate. The proposed monomer 1 is an achiral mixed phosphodiester and herein we report synthetic routes to 1 containing each of the four RNA bases. The solution
