A cat of all trades: A single copper catalyst promoted up to three reaction steps with separate catalytic cycles in a domino sequence (azide–alkyne cycloaddition/Goldberg amidation/Camps cyclization/(CHarylation)) for the rapid construction of complex heterocycles from three simple components under mild conditions (see scheme). Facile cleavage of the triazole ring enables further elaboration of the
