Abstract

Facile access to diverse C5-substituted imidazoles and oxazoles via sequential Van Leusen–Suzuki, Van Leusen–Heck, and Van Leusen–Sonogashira protocols, employing imidazolium-ILs as solvents along with piperidine-appended imidazolium [PAIM][NTf2] as task-specific basic IL has been demonstrated, in a high-yielding one-pot method, starting with readily available aldimines (for imidazole) or aldehydes (for oxazole) and tosylmethylisocyanide (Tos-MIC), under mild conditions with potential for recycling and reuse of the IL solvent. The scope of the method is supported 49 examples.
