The one-pot preparation of azanucleotide analogues from proline derivatives has been achieved by a sequential radical decarboxylation/phosphorylation process. The process proceeded under mild conditions, giving high yields of the nucleotide analogues. Remarkably, the stereoselectivity of the reaction can be controlled by using different oxygen and nitrogen substituents at C-4 to give preferentially
已经通过顺序自由基脱羧/磷酸化过程实现了从脯氨酸衍生物中一锅法制备氮杂核苷酸类似物。该过程在温和的条件下进行,核苷酸类似物的产量很高。值得注意的是,反应的立体选择性可以通过在 C-4 上使用不同的氧和氮取代基来控制,以优先得到 2,4-顺式或 2,4-反式产物。这样,非对映异构顺式/反式比例可以从 98:2 转变为 15:85。
