We report a novel and general method to access a highly under‐studied privileged scaffold—pyrimidines bearing a trifluoroborate at C4, and highlight the broad utility of these intermediates in a rich array of downstream functionalization reactions. This chemistry is underpinned by the unique features of the trifluoroborate group; its robustness provides an opportunity to carry out chemoselective reactions
我们报告了一种新颖且通用的方法来获得一种尚未得到充分研究的特殊支架——在 C4 处带有三氟硼酸盐的嘧啶,并强调了这些中间体在丰富的下游功能化反应中的广泛用途。这种化学反应以三氟硼酸盐基团的独特特征为基础;它的稳健性提供了在嘧啶上其他位置进行化学选择性反应的机会,同时在适当激活时提供了在 CB 键上进行精细化的途径。
