Prebiotic Synthesis of Simple Sugars by Photoredox Systems Chemistry

Abstract

A recent synthesis of activated pyrimidine ribonucleotides under prebiotically plausible conditions relied on mixed oxygenous and nitrogenous systems chemistry. As it stands, this synthesis provides support for the involvement of RNA in the origin of life, but such support would be considerably strengthened if the sugar building blocks for the synthesis--glycolaldehyde and glyceraldehyde--could be shown to derive from one carbon feedstock molecules using similarly mixed oxygenous and nitrogenous systems chemistry. Here, we show that these sugars can be formed from hydrogen cyanide by ultraviolet irradiation in the presence of cyanometallates in a remarkable systems chemistry process. Using copper cyanide complexes, the process operates catalytically to disproportionate hydrogen cyanide, first generating the sugars and then sequestering them as simple derivatives.

  • Ritson and Sutherland revealed a continuous reaction network starting from HCN that produces glycolaldehyde and glyceraldehyde driven by UV-photocatalytic irradiation of cyanocuprate complexes.

    “in 2012, Ritson and Sutherland [26] revealed a more continuous reaction network starting from HCN 1 that produces glycolaldehyde 4 and glyceraldehyde 5 in a chemical process driven by UV-photocatalytic irradiation of cyanocuprate complexes”

  • Irradiation of cyanocuprates photooxidises copper(I) to copper(II) generating a hydrated electron, which serves as a reducing agent.

    “irradiation of the cyanocuprates photooxidises the copper(I) centres to copper(II) generating in the process a hydrated electron (eaq−), which effectively serves as a reducing agent.”

  • Spontaneous hydrolysis of cyanogen yields cyanate, which reacts irreversibly with both glycolaldehyde and glyceraldehyde to form oxazolidinone rings.

    “Spontaneous hydrolysis of cyanogen yields cyanate, which reacts irreversibly, however, with both glycolaldehyde and glyceraldehyde to form oxazolidinone rings.”

  • Reversible addition of HCN to formaldehyde yields glycolonitrile, which can undergo reduction affording an imine that yields glycolaldehyde after hydrolysis.

    “Reversible addition of HCN to formaldehyde yields the cyanohydrin glycolonitrile 33, which like HCN 1 can also undergo reduction affording the imine that yields glycolaldehyde 4 after hydrolysis.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
