1,1,2-Ethenetriol: The Enol of Glycolic Acid, a High-Energy Prebiotic Molecule.

ABSTRACT: As low-temperature conditions (e.g. in space) prohibit reactions requiring large activation energies, an alternative mechanism for follow-up transformations of highly stable molecules involves the reactions of higher energy isomers that were generated in a different environment. Hence, one working model for the formation of larger organic molecules is their generation from high-lying isomers of otherwise rather stable molecules. As an example, we present here the synthesis as well as IR and UV/Vis spectroscopic identification of the previously elusive 1,1,2-ethenetriol, the higher energy enol tautomer of glycolic acid, a rather stable and hence unreactive biological building block. The title compound was generated in the gas phase by flash vacuum pyrolysis of tartronic acid at 400 °C and w
