Yang, Qing;Yan, Xiao-Tong;Feng, Cheng-Tao;Chen, De-Xiang;Yan, Zhong-Zhong;Xu, Kun research published 《 Tandem Strecker/C(sp3)-H amination reactions for the construction of cyanide-functionalized imidazo[1,5-a]pyridines with NH4SCN as a cyanating agent》, the research content is summarized as follows. An I2O5 promoted tandem Strecker/C(sp3)-H amination reaction of pyridine-2-carboxaldehydes, benzylamines and NH4SCN was reported. This multicomponent reaction that allowed the single-step construction of biol. important cyano-functionalized imidazo[1,5-a]pyridines with mol. diversity was realized for the first time. Moreover, the use of safe and easy-to-handle NH4SCN as a surrogate cyanating agent made this protocol appealing for potential applications.
