Pyrimidin‐6‐yl Trifluoroborate Salts as Versatile Templates for Heterocycle Synthesis

We report a novel and general method to access highly under-studied privileged scaffold—pyrimidines bearing trifluoroborate at C4, highlight the broad utility of these intermediates in rich array downstream functionalization reactions. This chemistry is underpinned by unique features group; its robustness provides an opportunity carry out chemoselective reactions other positions on pyrimidine while providing pathway for elaboration C−B bond when suitably activated.
