A process for synthesizing phosphoramidites by immobilizing a phosphitylating agent on an activated resin to create a loaded resin and then bringing the loaded resin into contact with a suitable substrate. The phosphoramidites are synthesized within minutes from applying the starting materials. Thus, the process makes it possible to create specific phosphoramidites on-demand as they are needed in further applications. The substrates to be applied are mostly nucleosides, thus to create nucleoside phosphoramidites for subsequent oligonucleotide synthesis.
一种合成
磷酰胺酯的过程,通过将
磷酰化剂固定在活化
树脂上形成负载
树脂,然后将负载
树脂与合适的基质接触。
磷酰胺酯从施加起始物质开始在几分钟内合成。因此,该过程使得可以根据需要在进一步应用中制备特定的
磷酰胺酯成为可能。待应用的基质主要是核苷酸,因此可用于后续寡核苷酸合成的核苷酸
磷酰胺酯。
