Minisci-type investigations on purines were limited to alkylations and arylations. Herein, we present the first method for the direct C–H amidation of a wide range of purines: xanthine, guanine, and adenine structures, including guanosine- and adenosine-type nucleosides. The Minisci-type reaction is also metal-free, cheap, operationally simple, scalable, and applicable to late-stage functionalizations of biologically
已开发出一种嘌呤的 C-H 羧基酰胺化方法,该方法能够直接安装伯、仲和叔酰胺。以前对嘌呤的 Minisci 型研究仅限于烷基化和芳基化。在此,我们提出了第一种对多种嘌呤进行直接 C-H 酰胺化的方法:黄嘌呤、鸟嘌呤和腺嘌呤结构,包括鸟苷和腺苷型核苷。Minisci 型反应还不含金属、便宜、操作简单、可扩展,适用于生物学重要分子的后期功能化。
