The prebiotic molecule glyceraldehyde is proposed to be formed from (Z)-1,2-ethenediol, a molecule recently detected toward the G+0.693-0.027 molecular cloud at the galactic center. In this work, we computationally simulate the formation of (Z)-1,2-ethenediol from vinyl alcohol on the surface of amorphous solid water in a two-step synthesis involving an OH addition and an H abstraction reaction. In total, we considered all reaction possibilities of the 1,1- and 1,2-OH addition to vinyl alcohol followed by H abstraction or H addition reactions on the resulting radicals. The combination of these reactions is capable of explaining the formation of (Z)-1,2-ethenediol provided a suprathermal diffusion of OH. We also conclude that our proposed formation pathway is not selective and also yields other abstraction and addition products. Key in our findings is the connection between the adsorption modes of the reactants and intermediates and the stereoselectivity of the reactions.Deutsche Forschungsgemeinschaft: EXC 2075 - 390740016 (Germany’s Excellence Strategy)Ministerio de Ciencia e Innovación (MCIN) / Agencia Estatal de Investigación (AEI): contrato Ramón y Cajal de Germán Molpeceres (RYC2022-035442-I) (MCIN/AEI/10.13039/501100011033 y el Fondo Social Europeo Plus)Japan Society: beca de promoción internacional de la investigación de Germán Molpeceres (P22013 y JP22F22013)Ministerio de Ciencia e Innovación (MCIN) / Agencia Estatal de Investigación (AEI): PID2020-117742GB-I00 (MCIN/AEI/10.13039/501100011033)German Research Foundation (DFG): INST 40/575-1 FUGG (JUSTUS 2 cluster)Research Center for Computational Science, Okazaki, Japan: 22-IMSC301 y 23-IMS-C128Proyecto Intramuros CSIC: 20245AT0162024info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.3847/1538-4357/ad6f9ahttps://uvadoc.uva.es/handle/10324/80096reponame:UVaDOC.
