Abstract
This unit describes a simple, reliable, and efficient chemical method for the synthesis of 5-(3-aminoallyl)-2′-deoxyuridine-5′-O -triphosphate (AA-dUTP) and 5-(3-aminoallyl)-uridine-5′-O -triphosphate (AA-UTP), starting from the corresponding nucleoside triphosphate. The presented strategy involves regioselective iodination of nucleoside triphosphate using N -iodosuccinimide followed by the palladium-catalyzed Heck coupling with allylamine to provide the corresponding (E )-5-aminoallyl-uridine-5′-O -triphosphate in good yields. It is noteworthy that the protocol not only provides a high-purity product but also eliminates the use of toxic mercuric reagents. © 2017 by John Wiley & Sons, Inc.
钯催化合成(E)-5-(3-氨基烯丙基)-尿苷-5′- o -三磷酸酯
本单元描述了一种简单、可靠、高效的化学合成5-(3-氨基烯丙基)-2 ' -脱氧尿苷-5 ' - o -三磷酸(AA-dUTP)和5-(3-氨基烯丙基)-尿苷-5 ' - o -三磷酸(AA-UTP)的方法,从相应的核苷三磷酸开始。提出的策略包括使用n -碘琥珀酰亚胺对三磷酸核苷进行区域选择性碘化,然后钯催化与烯丙胺进行Heck偶联,以高产出相应的(E)-5-氨基烯丙基尿苷-5′- o -三磷酸。值得注意的是,该方案不仅提供了高纯度的产品,而且还消除了有毒汞试剂的使用。©2017 by John Wiley &儿子,Inc。
