Heterocycles in one click: A novel organocatalytic enamide–azide cycloaddition reaction has been developed. This synthetic procedure represents a new method for the efficient construction of 1,4,5‐trisubstituted‐1,2,3‐triazoles under mild reaction conditions. Most significantly, the investigated process is highly regiospecific (see scheme).
