摘要
A new 1,4-amidocyanation of 1,3-enynes with N-amidopyridin-1-ium salts and TMSCN using a copper and photoredox synergetic catalysis for producingα-amido allenyl nitriles is developed.Employing N-amidopyridin-1-ium salts as the amidyl radical precursors,the reaction enables the formation of two new bonds,one C(sp^(3))-N bond and one C(sp^(2))-C(sp)bond,in a single reaction step.This reaction represents a mild,general route to the construction of theα-amido allenyl nitrile architectures,which characterizes a broad scope,a good functional group compatibility and an excellent selectivity.
