A new palladium-catalyzed method to prepare pyrroles directly from three basic building blocks-imines, alkynes, and acid chlorides-is described. This approach provides a straightforward method both to prepare pyrroles in one step and to diversify their structure by simple variation of any of the three starting materials. Mechanistic studies suggest that this process occurs via a complex series of eight

By sequencing the VanLeusenimidazole and oxazole syntheses with Suzuki, Heck and Sonogashira reactions, diverse libraries of C5‐functionalized imidazoles and oxazoles were synthesized in one‐pot reactions employing [BMIM][X] as a solvent and [PAIM][NTf2] as a base.
