A highly efficient direct C–H amination of BODIPYs has been accomplished through the Ag(I)-mediated nucleophilic addition of an amino radical to BODIPY at the C3- and/or C5-position and deprotonation processes under mild conditions. This protocol greatly streamlines the access to a variety of 3-aminated and 3,5-diaminated BODIPYs. The resulting BODIPYs with morpholine groups (3q and 4b) exhibit specific
BODIPYs的高效CH-H胺化反应是通过在Ag-(I)介导的C3-和/或C5位置上的氨基向BODIPY的亲核加成以及在温和条件下的去质子化过程完成的。该协议极大地简化了对各种3胺化和3,5胺化BODIPY的访问。产生的具有吗啉基团(3q和4b)的BODIPY表现出特定的内质网(ER)定位能力和可忽略的细胞毒性,这可能是潜在的ER靶向试剂。
