Enols—tautomers of ketones or aldehydes—are considered key intermediates in the formation of prebiotic sugars and sugar acids. Although laboratory simulation experiments suggest that enols should be ubiquitous in the interstellar medium, the unde

Cyclopropenone is one of few organic molecules detected in interstellar molecular clouds to date. Its formation mechanism from carbon monoxide and photoexcited acetylene is investigated, giving key insight into its formation in extreme conditions.

Glycolaldehyde is considered the entry point in the aqueous prebiotic formose (Butlerow) reaction although it mainly exists in its unreactive hydrated form in aqueous solution. The characterization of the more reactive nucleophilic enol form under in

Owing to the unique conditions in cold molecular clouds, enols-the thermodynamically less stable tautomers of aldehydes and ketones-do not undergo tautomerization to their more stable tautomers in the gas phase because they cannot overcome tautomeriz

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, and an exogenous delivery constitutes an appealing a

Acetaldehyde (CH3 CHO) is ubiquitous throughout the interstellar medium and has been observed in cold molecular clouds, star forming regions, and in meteorites such as Murchison. As the simplest methyl-bearing aldehyde, acetaldehyde constitutes a cri

The hitherto elusive oxaziridine molecule (cyclo-H2CONH) – an optically active, high energy isomer of nitrosomethane (CH3NO) – is prepared in processed methane–nitrogen monoxide ices and detected upon sublimation in the gas phase. Electronic st
