Abstract
Irradiation of solutions at pH 7 to pH 8.5 of orotic acid, orotidine, and orotidine 5'-phosphate with light at 254 nanometers yields the corresponding uracil derivative via the singlet excited state. This reaction completes a plausible prebiotic synthesis of uracil and its derivatives starting from HCN as the only carbon source.
摘要
在pH值为7至8.5的乳清酸、乳清苷和乳清苷5'-磷酸溶液中，用254纳米的光进行辐照，通过单重激发态产生相应的尿嘧啶衍生物。该反应完成了一个从HCN作为唯一碳源开始的、合理的尿嘧啶及其衍生物的前生物合成。
