The success of a one-step transformation of heterocyclic N-oxides to 2-alkyl-, aryl-, and alkenyl-substituted N-heterocycles hinges on the combination of copper catalysis and activation by lithium fluoride or magnesium chloride. The utility for the scaffold decoration of a broad range of complex N-heterocycles is exemplified by syntheses of new structural analogues of several antimalarial, antimicrobial, and fungicidal agents.
