Here we show that a primary amine can engage in the nucleophilic addition to an aldehyde to synthesize an alcohol following preactivation of the amine. The enabling reagent for this radical-polar crossover process is CrCl2. This reaction is selective for aldehydes and compatible with numerous functional groups, which are not tolerated under classical Grignard-type conditions. Complementary to the well-established
在这里,我们证明伯胺可以在胺预活化后与醛进行亲核加成来合成醇。这种自由基-极性交叉过程的促成试剂是 CrCl 2。该反应对醛具有选择性,并且与许多官能团相容,而这些官能团在经典格氏条件下是不耐受的。作为对成熟的亚胺合成的补充,这种脱氨基醇合成可以广泛扩展由醛和胺构建的化学空间。
