A base‐promoted net‐[3+2] cycloaddition of nitriles and 1‐arylpropynes for the synthesis of pyrroles is described. The developed method provides convenient access to various 2,5‐disubstituted or 2,4,5‐trisubstituted pyrroles in 40% to 96% yields (32 examples). Among methods for the synthesis of pyrroles, the protocol presented here stands out for its convenience and atom‐economy.
