Carbohydrates (CH2O)n are the formal adducts of carbon (atoms) to water with a repeating unit that structurally resembles H–C̈–OH (hydroxymethylene). Although hydroxymethylene has been suggested as a building block for sugar formation, it is a reactive species that had escaped detection until recently. Here we demonstrate that formaldehyde reacts with its isomer hydroxymethylene to give glycolaldehyde in a nearly barrierless reaction. This carbonyl–ene-type transformation operates in the… Expand
Interstellar Formation of Biorelevant Pyruvic Acid (CH3COCOOH)
Summary Pyruvic acid represents a key molecule in prebiotic chemistry to form metabolites and amino acids. Without liquid water on the early Earth, endogenous formation of pyruvic acid is unlikely,Expand
The Formation of C3O3H6 Structural Isomers in the Gas Phase through Barrierless Pathways: Formation and Spectroscopic Characterization of Methoxy Acetic Acid
Gas phase formation processes feasible at low temperatures are determined theoretically for 38 isomers obeying the C3O3H6 empirical formula, one of them, the simplest ketose dihydroxyacetone, hasExpand
Primary photodissociation mechanisms of pyruvic acid on S1: observation of methylhydroxycarbene and its chemical reaction in the gas phase.
The first evidence of a bimolecular reaction of MHC in the gas phase is presented, where MHC reacts with pyruvic acid to produce a C4H8O2 product, implying that some MHC produced from pyru Vic acid in Earth's troposphere will be stabilized and participate in chemical reactions with O2 and H2O, and should be considered in atmospheric modeling.

Formation of Glyoxylic Acid in Interstellar Ices: A Key Entry Point for Prebiotic Chemistry.
These studies unravel a key reaction path to glyoxylic acid, an organic molecule formed in interstellar ices before subliming in star-forming regions like SgrB2(N), thus providing a critical entry point to prebiotic organic synthesis. Expand
Autocatalysis in Formose Reaction and Formation of RNA Nucleosides.
These approaches provide a solution for the long-standing question of how the glycosidic bond is formed under the abiotic conditions with low energy barriers and appear to be the first nonenzymatic catalytic systems for formation of biomolecules. Expand
Prebiotic Sugar Formation Under Nonaqueous Conditions and Mechanochemical Acceleration
The results imply the possibility of a prebiotic monosaccharide origin in geochemical environments scant or devoid of water promoted by mechanochemical forces such as meteorite impacts or lithospheric activity. Expand
Preparation and characterization of the enol of acetamide: 1-aminoethenol, a high-energy prebiotic molecule†
This work presents the gas-phase synthesis of 1-aminoethenol, the higher-energy tautomer of acetamide, that has not been spectroscopically identified to date and was prepared by flash vacuum pyrolysis of malonamic acid and was characterized employing matrix isolation infrared as well as ultraviolet/visible spectroscopy.

Mechanistic investigations on Pinnick oxidation: a density functional theory study
Frontier molecular orbital analysis, intrinsic reaction coordinate, molecular dynamics and distortion/interaction analysis further supported the proposed mechanism and showed that hydrogen bonding between carbonyl and t-butanol is unlikely to occur. Expand

Capture of hydroxymethylene and its fast disappearance through tunnelling
The synthesis of hydroxymethylene and its capture by matrix isolation is reported, finding that H–C–OH rearranges to formaldehyde with a half-life of only 2 h at 11 K by pure hydrogen tunnelling through a large energy barrier in excess of 30 kcal mol–1. Expand
Linked strategy for the production of fuels via formose reaction

Rates of decomposition of ribose and other sugars: implications for chemical evolution.
The results suggest that the backbone of the first genetic material could not have contained ribose or other sugars because of their instability, and the generally accepted prebiotic synthesis of ribose, the formose reaction, yields numerous sugars without any selectivity. Expand
