The reactions of Schiffbases such as N-benzylideneanilines with superoxide ion in acetonitrile under mild conditions gave the cyanomethyl adducts, 3-arylamino-3-arylpropionitriles, as the main products in relatively good yields. In the case of N-(4-nitrobenzylidene)aniline, the adduct was further oxidized to β-anilino-4-nitrocinnamonitrile. No oxidative products such as amides were obtained except

β-Amino nitriles are important molecular scaffolds. Cyanoalkylation of imines is the most straightforward method for the construction of these scaffolds. In this study, we report the novel cyanoalkylation of imines via radical coupling enabled by a photoactive electrondonor–acceptorcomplex. This strategy is characterized by mild conditions, broad reaction scopes, and high atom economy. The scalability
β-氨基腈是重要的分子支架。亚胺的氰烷基化是构建这些支架的最直接的方法。在这项研究中,我们报道了通过光敏电子供体-受体复合物实现的自由基偶联实现亚胺的新型氰烷基化。该策略具有条件温和、反应范围广、原子经济性高等特点。该策略的可扩展性和实用性通过 40 g 连续流动系统得到了证明,从中获得了多种重要的药物相关分子。
