Abstract: Three synthons: methylene, nitrene and carbon monoxide form aziridinone in the presence of molecular nitrogen at low temperatures. This one, in contact with the same three synthons could form the precursors of the first proteinogenic amino acids. This paper is a theoretical, thermodynamically and reactivity study concerning the formation of the three previously named amino acids at low temperature conditions. The key intermediates are identified in the formation of the three amino acids: aziridinone, aziridino… Show more

“…The enthalpies of formation of all the radical intermediates and of neutral molecules, reactants or final reaction products were calculated first. In previous works [6,7], quantitative data on C-methylaziridinonyl radical 11 (table 1) were presented in detail. Shortly, it would be obtained from the Caziridinonyl radical and methylene.…”

“…In previous works [6,7], we have shown how the following proteinogenic amino acids can be obtained: glycine, alanine, serine, cysteine, aspartic acid, asparagine and threonine. In this paper we continue the construction of four further proteinogenic amino acids: valine, leucine, isoleucine and methionine.…”

“…Previously [1,2] it was shown that aziridinonil radical may be formed by several reactions involving the different molecular radically systems. We can remember only the reaction between aziridinone and methylene in singlet state.…”

“…In previous papers [1,2], we proposed a model for the formation of the first proteinogenic amino acids. At the basis of these amino acids formation would be three syntones: methylene, nitrenes and carbon monoxide.…”
