The synthesis of functionalized nitriles via microwave‐promoted radical fragmentations of cyclic O‐phenyl oxime ethers is reported. A variety of radical traps can be employed, permitting the generation of diverse adducts via C−O, C−C, C−N, or C−X bond formation. Other salient features include a simple and practical protocol, very short reaction times, and the avoidance of metal catalysts and toxic
据报道,通过微波促进环状的O-苯基肟醚的自由基断裂,可以合成功能化的腈。可以使用多种自由基陷阱,从而允许通过C-O,CC,CN或C-X键形成多种加合物。其他显着特征包括简单实用的方案,非常短的反应时间以及避免使用金属催化剂和有毒的氰化物试剂。通过类固醇衍生的底物的环畸变证明了该方法的实用性。
