A recent synthesis of activated pyrimidine ribonucleotides under prebiotically plausible conditions relied on mixed oxygenous and nitrogenous systems chemistry. As it stands, this synthesis provides support for the involvement of RNA in the origin of life, but such support would be considerably strengthened if the sugar building blocks for the synthesis—glycolaldehyde and glyceraldehyde—could be shown
最近在益生元合理条件下合成活化的嘧啶核糖核苷酸依赖于混合含氧和含氮系统化学。就目前而言,这种合成为 RNA 参与生命起源提供了支持,但如果可以证明合成的糖构建块——乙醇醛和甘油醛——源自一种碳原料分子,则这种支持将得到显着加强。类似的混合含氧和含氮系统化学。在这里,我们展示了这些糖可以在显着的系统化学过程中在氰基金属酸盐存在下通过紫外线照射由氰化氢形成。使用氰化铜配合物,该工艺通过催化作用使氰化氢歧化,
