## Abstract A variety of bicyclic __N__,__N__‐disubstituted 2‐aminopyridines have been prepared from diynes and cyanamides by nickel‐catalyzed [2+2+2] cycloaddition reactions. The reactions proceeded at room temperature with low catalyst loading to afford 2‐aminopyridines in good to excellent yield
