RNA Oligomerisation without Added Catalyst from 2′,3′‐Cyclic Nucleotides by Drying at Air‐Water Interfaces** Without catalyst! A non-enzymatic, spontaneous route to the formation of short, mixed-sequence RNA strands from 2′,3′-cyclic ribonucleotides is shown. The reaction occurs by drying at the air–water i...
