This review highlights some remarkable recently made achievements in the application of palladium‐mediated processes to the design of multicomponent one‐pot syntheses of heterocyclic compounds. Palladium‐catalysed cascade reactions are surveyed, together with processes based on sequential, one‐pot performance of individual transformations in which at least one is catalysed by palladium.

Versatile strategies of multicomponent coupling reactions to synthesize variously substituted pyrroles 1 are summarized. These heterocycles are important targets as molecules in their own right, for their pharmacological properties, as well as intermediates for more elaborate syntheses.
