The plausible prebiotic availability of 6-aminopyrimidines makes the formation of purine nucleosides by Traube reaction an interesting pathway to explore. However, the formation of a pterin ring is the preferred outcome relative to purine nucleoside synthesis, which requires a high sugar excess to be significant. We show that a urea-based solvent is a suitable medium for the formylation, synthesis
6-氨基嘧啶的看似合理的益生元可用性使得通过特劳贝反应形成嘌呤核苷成为一个值得探索的有趣途径。然而,相对于嘌呤核苷合成,蝶呤环的形成是优选的结果,嘌呤核苷合成需要高糖过量才能显着。我们表明,基于脲的溶剂是甲酰化、嘌呤/蝶呤环的合成以及随后的磷酸化的合适介质。
