The natural products PreQ 1 , PreQ 0 , and archaeosine are deazaguanosine-derived natural products of immense biological importance. All three are critical components of tRNAs and, as such, are involved in decoding genetic information. We were able to consolidate and shorten the syntheses of all three compounds by using a novel Turbo-Grignard-based approach. The reported iodine/magnesium exchange followed
天然产物 PreQ 1 、PreQ 0 和古菌素是具有巨大生物学重要性的脱氮鸟苷衍生的天然产物。这三个都是 tRNA 的关键组成部分,因此,都参与解码遗传信息。通过使用基于 Turbo-Grignard 的新型方法,我们能够巩固和缩短所有三种化合物的合成。报道的碘/镁交换以及与脱氮鸟苷骨架的格氏反应显示出对重要官能团(如酯和酰胺)的高度耐受性。
